Mahler Measure and Entropy |
Presenter: |
Klaus Schmidt, University of Vienna / Schrodinger Institute |
Date: |
Wednesday, October 11, 2006, Time: 4:30 p.m., Location: Fine 314 |
Abstract: |
One can associate canonically and very simply with every ideal $I$ in the integral group ring $\mathbf{Z}[\mathbf{Z}^d], d\ge 1$, a measure preserving action $\alpha = \alpha _I$ of $\mathbf{Z}^d$ by automorphisms of a compact abelian group $X=X_I$ (or an 'algebraic' $\mathbf{Z}^d$-action for short). There are many interesting correspondences between algebraic properties of the ideal $I$ and dynamical properties of $\alpha _I$. This lecture will focus on one of these connections: if the ideal $I$ is principal and generated by an element $f\in \mathbf{Z}[\mathbf{Z}^d]$, then the entropy of $\alpha _I$ is the logarithm of the Mahler measure of $f$. Mahler measures of multivariate polynomials $f\in \mathbf{Z}[\mathbf{Z}^d]$ and, in particular, certain values of $L$-functions, also occur as entropies of certain lattice models (especially dimer models) in statistical mechanics, and the connection between these lattice models and the algebraic $\mathbf{Z}^d$-actions associated with the principal ideals generated by these polynomials is still somewhat mysterious. The connection between ideals in the integral group ring $\mathbf{Z}[\Gamma ]$ of a discrete group $\Gamma $ and algebraic $\Gamma $-actions also extends in a straightforward way to arbitrary discrete (amenable) groups. For principal ideals the entropy of these actions is a quantity which extends the notion of logarithmic Mahler measure to elements of $\mathbf{Z}[\Gamma ]$. The last part of the lecture will discuss what little is currently known about this extension. Much of this material is joint work with Christopher Deninger and/or Doug Lind. |

Spectral localization in the hierarchical Anderson model |
Presenter: |
Eugene Kritchevski, McGill University, Montreal |
Date: |
Thursday, October 12, 2006, Time: 2:00 p.m., Location: Fine 401 |
Abstract: |
The hierarchical Anderson model is a discrete random self-adjoint operator H=L+cV acting on l2(X), where X is a countable set, L is a hierarchical Laplacian, V is a random potential given by (Vf)(x)=v_x f(x) with v_x i.i.d. random variables, and c>0 is a coupling constant. S. Molchanov has proven that the spectrum of H is pure point with probability one, when the random variables v_x have a Cauchy distribution. In this talk, I will review the basic properties of the model and I will present two localization theorems extending Molchanov's result. Theorem 1: if the spectral dimension of the model is less or equal than 4, then, for any continuous distribution of v_x, the spectrum of H is pure point with probability one. Theorem 2: for a dense set of distributions of v_x, H has pure point spectrum with probability one, in any spectral dimension. |

Abstract: |
I'll discuss the structure of Khovanov and Rozansky's HOMFLY homology, with an emphasis on what we can (and can't) learn about the theory from skein exact sequences. An important ingredient is a "reduced" version of the HOMFLY homology for links. This theory behaves in a manner analogous to knot Floer homology. |

Concentration phenomena for singularly perturbed equations |
Presenter: |
Andrea Malchiodi, SISSA, Trieste |
Date: |
Friday, October 13, 2006, Time: 3:00 p.m., Location: Fine 314 |
Abstract: |
We consider some classes of singularly perturbed elliptic equations, arising from the study of the NLS or from reaction- diffusion systems. We characterize the asymptotic behavior of some solutions in terms of stationarity properties of the limit sets. Resonance phenomena occur in general, and the analysis presents analogies to the study of collapsing CMC surfaces. |

One sketch for all: a sublinear approximation scheme for heavy hitters |
Presenter: |
Anna Gilbert, Mathematics, University of Michigan |
Date: |
Monday, October 16, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
The heavy hitters problem elicits a list of the m largest-magnitude components in a signal of length d. Although this problem is easy when the signal is presented explicitly, it becomes much more challenging in the setting of streaming data, where the signal is presented implicitly as a sequence of additive updates. One approach maintains a small sketch of the data that can be used to approximate the heavy hitters quickly. In previous work, this sketch is essentially a random linear projection of the data that fails with small probability for each signal. It is often desirable that the sketch succeed simultaneously for ALL signals from a given class, a requirement that may be called uniform heavy hitters. It arises, for example, when the signal is queried a large number of times or when the signal updates are stochastically dependent.
This talk describes a random linear sketch for uniform heavy hitters that succeeds with high probability. The recovery algorithm produces a list of heavy hitters that approximates the input signal with an l2 error that is optimal, except for an additive term that depends on the optimal l1 error and a controllable parameter e. The recovery algorithm requires space m*poly(log(d)/e) and time m2*poly(log(d)/e) to produce the list of heavy hitters. Up to logarithmic factors, the performance of this algorithm is the best possible with respect to several resources.

Generalizations of the Shafarevich Conjecture |
Presenter: |
Sándor Kovács, University of Washington |
Date: |
Tuesday, October 17, 2006, Time: 4:30 p.m., Location: Fine 322 |
Abstract: |
At the 1962 ICM Shafarevich made a conjecture that predicted that for a fixed base and a fixed genus there are only finitely many non-isotrivial families of smooth projective curves of the given genus over the given base. This was proven in the function field case by Parshin (for a compact base) and by Arakelov (in general), and in the number field case by Faltings. In this talk I will discuss various higher dimensional generalizations of the function field case including Viehweg's conjecture and recent results in the area. |

Ising models with long range competing interactions: striped nature of the ground states |
Presenter: |
Alessandro Giuliani, Princeton University |
Date: |
Tuesday, October 17, 2006, Time: 4:30 p.m., Location: Jadwin 343 |
Abstract: |
I will consider a d-dimensional Ising model with nearest neighbor ferromagnetic interaction and a long range antiferromagnetic interaction, decaying as the distance to the power -(d+1). In 1D I will show that the ground state is periodic, consisting of ferromagnetic blocks of alternating magnetization. I will then discuss partial results for the multidimensional case, for which a similar phenomenon of spontaneous stripe formation in the ground state has been conjectured. The talk is based on joint work with Joel Lebowitz and Elliott Lieb. |

Dilute quantum gases |
Presenter: |
Robert Seiringer, Princeton University |
Date: |
Wednesday, October 18, 2006, Time: 4:30 p.m., Location: Fine 314 |
Abstract: |
We present an overview of mathematical results on the low temperature properties of dilute quantum gases, which have been obtained in the past few years. The discussion includes, for instance, results on the free energy in the thermodynamic limit, and on Bose-Einstein condensation, Superfluidity and quantized vortices in trapped gases. All these properties are intensely being studied in current experiments on cold atomic gases. We will give a brief description of the mathematics involved in understanding these phenomena, starting from the underlying many-body Schroedinger equation. |

Two optimization problems arising from polling and nonhomogeneous poisson processes |
Presenter: |
Jonathan Eckstein, Rutgers University |
Date: |
Wednesday, October 18, 2006, Time: 4:30 p.m., Location: E-219, E-Quad |
Abstract: |
This talk presents two optimization problems arising from the same applied probability application, in which we monitor an information source to which data are added at times modeled by a nonhomogeneous Poisson process. In the first application, we suppose that the arrival rate function is known and we may poll the information source a limited number of times over some planning horizon. We develop an objective function for evaluating the quality of a polling schedule, and approximately optimize it by a combination of dynamic programming and local search. The dynamic programming algorithm uses a discrete time approximation for which we are able to prove quality guarantees. The second application addresses the more fundamental problem of estimating the arrival rate function of a nonhomogeneous Poisson process. We argue that nonnegative splines constitute an attractive class of functions over which to search, and show that maximum likelihood estimation over this class reduces to convex optimization over semidefinite cone and linear constraints. In particular, estimation by cubic splines reduces to convex nonlinear programming. We present numerical results in which we use a cross-validation procedure to set the number of spline knots. Our general approach can easily be adapted to density estimation and other related problems. Various portions of this work joint with: Farid Alizadeh, Avigdor Gal, Nilay Noyan, Gabor Rudolf. |

Distributional properties of cocycles and stationary random walks |
Presenter: |
Klaus Schmidt, Schroedinger Institute |
Date: |
Thursday, October 19, 2006, Time: 2:00 p.m., Location: Fine 401 |
Abstract: |
If $(X_n)$ is an ergodic stationary stochastic process and $Y_n=X_0+\dots + X_{n-1}$ the associated random walk, what can be said about recurrence of $(Y_n)$ if one only knows the distributions of the $Y_n,n\ge1$? This question immediately translates in to a question about Birkhoff sums for ergodic transformations, and by using methods from ergodic theory (orbit equivalence) one can prove for $d=2$, for example, that $(Y_n)$ is recurrent whenever it satisfies a very weak form of the central limit theorem. Another result about distributional properties of cocycles is the following: let $T$ be a measure-preserving and ergodic transformation of a probability space $(X,\mu )$, $f$ a positive real valued Borel map with $\int f\,d\mu =1$, and let $T^f$ be the flow under the function $f$ with base $T$. If $T$ is mixing and $T^f$ is weakly mixing, or if $T$ is ergodic and $T^f$ is mixing, then the Birkhoff sums $f(n,.),\,n\ge0$, of $f$ 'disperse'. |

Solving Nasty Optimization Problems in Science and Engineering |
Presenter: |
Margaret Wright, Computer Science Department, CIMS, New York University |
Date: |
Monday, October 23, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
Many important optimization problems in science and engineering involve functions that can fairly be described as "nasty", which can mean any or all of wildly nonlinear, nonsmooth, noisy, and defined through complex black-box simulation or error-prone experimental data. Because it is often impossible or impractical to calculate derivatives of these functions, non-derivative methods are the only feasible choice. These methods are in the midst of a renaissance involving research on their theoretical and computational properties, as well as investigation of which methods are best suited for which applications. This talk will include examples of challenging problems along with the speaker's assessment of the state of the art in non-derivative optimization methods.

A fictitious play approach to complex systems optimization |
Presenter: |
Robert Smith, University of Michigan |
Date: |
Tuesday, October 24, 2006, Time: 4:30 p.m., Location: E-219, E-Quad |
Abstract: |
Complex systems consisting of a large number of interacting components are in practice increasingly modeled through computer simulations rather than via traditional equation based approaches. The resulting model typically allows for little or no structural assumptions on the form of the objective function or constraints, thus posing a challenging optimization problem. We explore in this talk a novel optimization paradigm inherited from game theory that animates the components of the system within a non-cooperative game of identical interest. The optimizations take place though individual best replies of the players, thus vastly reducing the dimensionality of the optimization problems solved (the components’ joint interactions are reflected indirectly through their shared objective function). We will illustrate the approach by discussing an application to a joint production systems optimization project within the GM Collaborative Research Laboratory at the University of Michigan. |

Information Theory and Probability Estimation: From Shannon to Shakespeare via Laplace, Good, Turing, Hardy, Ramanujan, and Fisher |
Presenter: |
Alon Orlitsky, ECE and CSE, University of California, San Diego |
Date: |
Monday, November 6, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
Standard information-theoretic results show that data over small, typically binary, alphabets can be compressed to Shannon's entropy limit. Yet most practical sources, such as text, audio, or video, have essentially infinite support. Compressing such sources requires estimating probabilities of unlikely, even unseen, events, a problem considered by Laplace. Of existing estimators, an ingenious if cryptic one derived by Good and Turing while deciphering the Enigma code works best yet not optimally. Hardy and Ramanujan's celebrated results on the number of integer partitions yield an asymptotically optimal estimator that compresses arbitrary-alphabet data patterns to their entropy. The same approach generalizes Fisher's seminal work estimating the number of butterfly species and its extension authenticating a poem purportedly written by The Bard. The talk covers these topics and is self contained.

Irrational triangular billiards |
Presenter: |
Richard Schwartz, Brown University |
Date: |
Wednesday, November 8, 2006, Time: 4:30 p.m., Location: Fine 314 |
Abstract: |
It is an old and open problem whether or not every triangular shaped billiard table has a periodic billiard path. The answer is known to be yes for acute, right, and rational triangles but unknown in the obtuse irrational case. Over several years, Pat Hooper and I have developed a graphical user interface, called McBilliards, with a view towards resolving the triangular billiards problem. The huge experimental output from the progran illustrates the extreme and previously unexpected complexities of the problem. In my talk I will survey the experimental evidence from McBilliards and also explain some of our rigorous results which were inspired by the experiments. |

We prove that the quintic (critical) defocussing wave equation with Dirichlet boundary conditions in a 3-d bounded domain is globally well posed in energy space. The main ingredient of the proof is an (optimal) Strichartz inequality derived from some recent spectral projector estimates by Smith and Sogge and a precise study of the boundary value problem.

Denoising Color Images |
Presenter: |
Yang Wang, Mathematics, Georgia Institute of Technology |
Date: |
Monday, November 13, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
Natural color images captured by digital cameras often exhibit noticeable noise, particularly when the pictures are taken under low lighting or artificial lighting conditions. Traditional denoising techniques, which are often tested for removing artificial noise in monochromatic images, often do not work well for noisy color images.
In this talk, we present an overview of some of the traditional methods for denoising. We discuss a new strategy, which we call the cross-channel principle, that can be applied for very effective denoising of color images. In particular we show how this principle can be applied to the total variation denoising scheme and an ENO type denoising scheme.

Is every coherent sheaf on an algebraic variety the quotient of a locally free sheaf of finite rank? I will discuss an investigation of this question via equivariant vector bundles on toric varieties, and will give examples of complete (singular, nonprojective) toric threefolds with no nontrivial equivariant vector bundles of rank less than or equal to 3. It is not known whether these varieties have any nontrivial vector bundles at all. |

Abstract: |
A new proof of the convergence of the N-particle Schroedinger dynamics for bosons towards the dynamics generated by the Hartree equation in the mean-field limit. For a restricted class of two-body interactions, we obtain convergence estimates uniform in h- bar, up to an exponentially small remainder. For h-bar = 0, the classical dynamics in the mean-field limit is given by the Vlasov equation. (Joint work with J.Froehlich and S.Schwarz.) |

Abstract: |
Selective excitation is an essential ingredient of any application of nuclear magnetic resonance, e.g. MR-imaging or spectroscopy. I will explain how the problem of selective excitation of 2-level quantum systems leads directly to the classical inverse scattering problem for the 2x2 AKNS system. We discuss the analysis of the inverse scattering transform and the role of non-linearity. I then show how a viable numerical algorithm, based on the hard pulse approximation, allows for the practical and accurate solution of this problem. |
