| Presenter: | Manfred Einsiedler, Princeton University |
| Date: | Thursday, March 10, 2005, Time: 2:00 p.m., Location: Fine Hall 322 |
| Abstract: | In joint work with E. Lindenstrauss we obtained a complete classifications of joinings of higher rank Cartan actions on locally homogeneous spaces. Unlike the case of torus actions, here there is no 'up to zero entropy part' in the classification -- every ergodic joining is algebraic. Previous results in that direction required additional assumptions. We will discuss the proof and a reformulation as an equidistribution - result. |

| Presenter: | Sa'ar-David Hersonsky, Princeton University |
| Date: | Thursday, March 10, 2005, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | Inspired by the theory of Diophantine approximation of a real (or complex) number by rational ones, we develop a theory of approximation of geodesic lines in a negatively curved Riemannian manifold. The talk will be a survey on some of our results: We prove a Dirichlet type theorem, define a Hurwitz type constant in terms of the lengths of closed geodesics, and a Khintchine-Sullivan type theorem on the Hausdorff measure of the geodesic lines starting from a cusp that are well approximated by cusp returning ones. This is a joint project with Frederic Paulin (ENS-Paris). |

| Topic: | Finite frames and quantum detection |
| Presenter: | John Benedetto, University of Maryland |
| Date: | Monday, March 21, 2005, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | We discuss quantum measurement in terms of positive operator-valued measures (POMs). For any tight frame with frame constant 1 for a separable Hilbert space there is an associated POM. Our setup is d-dimensional Hilbert space H and frames for H consisting of N elements. H represents a physical system, and it is known that the state x of the system is in E, a set of N given possible states. The problem is to perform a measurement in order to determine x. This is equivalent to constructing a POM on the subsets of E with a natural probabilistic property. Because of the relationship with frames, the problem reduces to constructing a tight frame with frame constant 1 which minimizes a probability of detection functional defined in terms of E. A compactness argument shows the existence of a solution. We solve the problem using techniques from Lagrangian mechanics and properties of SO(N) with the goal of constructing solutions numerically from the resulting equations. Geometrically uniform and Grassmannian frames are natural background material. This is a collaboration with Andrew Kebo. |

| Presenter: | Robin Graham, University of Washington, Seattle |
| Date: | Tuesday, March 22, 2005, Time: 4:00 p.m., Location: Fine Hall 1201 |
| Abstract: | This talk will describe an analogue of a Dirichlet to Neumann map for Poincar\'e-Einstein metrics, also known as asymptotically hyperbolic or conformally compact Einstein metrics. An explicit identification of the linearization of the map at the sphere will be given for even interior dimensions, together with applications to the structure of the map near the sphere and to a different proof of the positive frequency conjecture of LeBrun which was resolved by Biquard. |
| Algebraic Geometry Seminar | |
| Topic: | Hodge type, divisibility of eigenvalues of Frobenius and slopes |
| Presenter: | H. Esnault, Essen |
| Date: | Tuesday, March 22, 2005, Time: 4:30 p.m., Location: Fine Hall 322 |
| Abstract: | We discuss Deligne's philosophy of the relation between Hodge filtration and congruences for points over finite fields. 1-st example: Lang-Manin conjecture: Fanos over finite field have points (via motivic cohomology) 2-st example: unequal characteristic: Hodge type vanishing in dim 2 over p-adic field implies points in the mod p-reduction. In higher dimension we have to replace the Hodge type condition by a coniveau condition. The theorem is based on Deligne's integrality theorem over a fintie field and its extesnion (jointly with him) over a local field. 3-rd example: slopes in rigid cohomology (joint with Berthelot-Bloch): 2 thetas divisors on an abelian variety over the finite field $\F_q$ have the same number of points mod q. The theorem relies on a theorem describing how to compute the slope $[0 \1[$ part of rigid cohomology. It has other applications, eg a vanishing theorem combining Serre's and Kodaira's vanihsing theorem in char. p. |

| Presenter: | Bin Yu, University of California, Berkeley |
| Date: | Tuesday, March 22, 2005, Time: 4:30 p.m., Location: Room E-219, Engineering Quad |
| Abstract: | Information technology advances are making data collection possible in most if not all fields of science and engineering and beyond. Statistics as a scientific discipline is challenged and enriched by the new opportunities resulted from these high-dimensional data sets. In this talk, I will use serveral research projects to demonstrate how these IT challenges are met by finding new applications of traditional statistical thinking and methods and by incorporating compression and computation considerations into statistical estimation. In particluar, I will cover cloud detection over the polar region, microarray image compression for statistical analysis, and L2 boosting as a computationally efficient method for sparse nonparametric regression model fitting. |

| Presenter: | E. Viehweg, Essen |
| Date: | Tuesday, March 29, 2005, Time: 4:30 p.m., Location: Fine Hall 322 |
| Abstract: | Let $Y$ be a non-singular projective manifold with an ample canonical sheaf, and let $V$ be a rational variation of Hodge structures of weight one on $Y$ with Higgs bundle $E^{1,0}+E^{0,1}$. If $Y$ is a curve the Arakelov Inequality says that $\mu(E^{1,0})-\mu(E^{0,1})$ is smaller than or equal to the degree of the canonical sheaf. The equality implies that $V$ is the tensor product of a unitary bundle and the rank two variation of Hodge structures given by a theta characteristic; moreover $Y$ is the Shimura curve corresponding to $V$. We will discuss similar inequalities for surfaces $Y$. Here the equality will imply that $Y$ is either a compact Hilbert modular surface, or a ball quotient, and again $V$ is the tensor product of a canonical uniformizing variation of Hodge structures with a unitary bundle. Most of the results extend to variation of Hodge structures over quasi projective manifolds with a "nice" compactification and partly to the higher dimensional case. (joint work with Kang Zuo). |

| Abstract: | The purpose of the talk is to explain how effective estimates for the Markoff spectrum in dimensions 3 and 4 can be obtained using expanding properties for the actions of semisimple Lie groups on the quotients by arithmetic subgroups. These expanding properties follow from the spectral gap for the Laplace operator. |

| Presenter: | Jacob Rasmussen, Princeton University |
| Date: | Thursday, March 31, 2005, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | The Khovanov homology is a homological generalization of the Jones polynomial. The technique of deforming the definition of this theory was introduced by Lee and studied in the sl(n) case by Gornik. It has proven to be a very powerful one. In this talk I'll describe the space of possible deformations, and give some applications, both to computing the sl(n) theory and to better understanding its structure. |

| Topic: | 33 Years of Bin Packing |
| Presenter: | David Johnson, AT&T |
| Date: | Monday, April 4, 2005, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | In the bin packing problem, one is given a list of 1-dimensional items and asked to pack them into a minimum number of unit-capacity bins. This was one of the first NP-hard problems to be studied from the "approximation algorithm" point of view, and over the years it has served as a laboratory for the study of new questions about approximation algorithms and the development of new techniques for their analysis. In this talk I present a brief survey of this history, covering worst-case, average-case, and experimental results. The latter have led to many interesting conjectures and theorems, as well as the new "sum-of-squares" algorithm for the problem. |

| Topic: | Useful Bounds on the Expected Maximum of Correlated Normal Variables |
| Presenter: | Andrew Ross, Lehigh University |
| Date: | Tuesday, April 5, 2005, Time: 4:30 p.m., Location: Room E-219, Engineering Quad |
| Abstract: | We compute useful upper and lower bounds on the expected maximum of up to a few hundred correlated Normal variables with arbitrary means and variances. Two types of bounding processes are used: perfectly dependent Normal variables, and independent Normal variables, both with arbitrary mean values. The expected maximum for the perfectly dependent variables can be evaluated in closed form; for the independent variables, a single numerical integration is required. Higher moments are also available. We use mathematical programming to find parameters for the processes, so they will give bounds on the expected maximum, rather than approximations of unknown accuracy. Our original application is to the maximum number of people on-line simultaneously during the day in an infinite-server queue with a time-varying arrival rate. The upper and lower bounds are tighter than previous bounds, and in many of our examples are within 5 percent of each other. |

| Topic: | The Inverse Problem in Invariant Theory |
| Presenter: | Michael Larsen, Indiana University |
| Date: | Wednesday, April 13, 2005, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | The direct problem in invariant theory is to describe the category of representations of a given group. Its inverse is to extract information about a group from information about its representations. The prototypical result in this direction is Tannaka duality. The ultimate goal is to recognize compact Lie groups which appear in nature, where in practice one typically does not know the category of representations up to isomorphism. |

| Presenter: | Ayelet Lindenstrauss, Indiana University |
| Date: | Thursday, April 14, 2005, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | This talk is about joint work with Randy McCarthy (UIUC). We give a method for finding the completion at a prime p of the reduced (over A) K-theory of the square-zero extension of A by a free A-module of finite rank, $\tilde K(A \semiprod (A^{\oplus k}))^\wedge _p$. The calculation is carried out when $A$ satisfies a technical condition which (by work of Hesselholt and Madsen) is satisfied by perfect fields of characteristic $p$, and in that case generalizes the dual numbers ($k=1$) case which Hesselholt and Madsen calculate by different methods. Our calculation uses an invariant we call $W(A;M)$, which can be thought of as a Witt ring of $A$ with coefficients in $M$, or alternatively as cyclic homology of $A$ with coefficients in $M$. By Goodwillie calculus methods, $\tilde K (A \semiprod M) \simeq W(A;M\otimes S1)$, so what we actually study is $W(A; A^{\oplus k}\otimes S1)$. The completion at $p$ is needed for a topological analog of breaking the Witt ring down into a product of $p$-Witt vectors. |

| Topic: | Probabilistic reasoning and Ramsey Theory |
| Presenter: | Benjamin Sudakov, Princeton University |
| Date: | Wednesday, April 20, 2005, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | "Ramsey Theory" refers to a large body of deep results in mathematics concerning the partition of large collections. Its underlying philosophy is captured succinctly by the statement that "In a large system complete disorder is impossible". Since the publication of the seminal paper of Ramsey in 1930, this subject has grown with increasing vitality, and is currently among the most active areas in Combinatorics. An important factor in the development of Ramsey Theory was the successful application of the so-called "Probabilistic Method". This method was initiated more than fifty years ago by Paul Erdos, and became one of the most powerful and widely used tools in Discrete Mathematics. In this talk I will describe some classical results of Ramsey Theory together with recent progress on some old questions of Erdos which was made using probabilistic arguments. I will also discuss the problem of converting existence arguments into deterministic constructions, in particular, the recent explicit constructions of Bipartite Ramsey graphs. |

| Presenter: | Sergio Verdu, Applied Mathematics and Electrical Engineering, Princeton University |
| Date: | Monday, April 25, 2005, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | Finite-alphabet signals corrupted by discrete noisy channels arise naturally in a wide range of applications spanning fields such as statistics, engineering, and computer science. Examples include DNA sequence analysis and processing, text correction, Hidden Markov model state estimation, and image denoising. While the field of filtering or denoising of continuous-alphabet signals has a long history, the field of discrete denoising has seen far less progress. In many discrete denoising applications, a good model for the randomness of the noisy channel is known, whereas the statistical description of the noiseless signal is either unknown or too complex. It is therefore of considerable interest to pose the problem of discrete universal denoising where no knowledge exists about the statistics of the noiseless signal while the channel statistics are assumed known. I will present the DUDE algorithm for discrete universal denoising which has linear complexity and attains universal optimality in a stochastic sense as well as a stronger semi-stochastic sense. I will also show several DUDE-based algorithms for channel decoding of systematically encoded redundant data. Joint work with E. Ordentlich, G. Seroussi, M. Weinberger and T. Weissman. |

| Presenter: | Michael Fu, University of Maryland |
| Date: | Tuesday, April 26, 2005, Time: 4:30 p.m., Location: Room E-219, Engineering Quad |
| Abstract: | We survey the methods of stochastic gradient estimation, including perturbation analysis, the likelihood ratio method, and weak derivatives. We illustrate the techniques using models in queueing, inventory, and finance. In the latter case, the methods can be used for estimating the so-called Greeks, which are crucial for hedging, and also for pricing American-style options (derivatives with early exercise opportunities). Computational examples using the estimators in stochastic approximation algorithms are described. |
