Green-Tao's result on arithmetic progressions in the primes: ergodic part of the proof |
Presenter: |
Ilya Shkredov, I.A.S. / Moscow State University |
Date: |
Thursday, October 18, 2007, Time: 2:00 p.m., Location: Fine Hall 401 |
Abstract: |
Recent and beautiful theorem of Ben Green and Terence Tao asserts that the primes contain arithmetic progressions of any length. The proof has two parts.
In the first part Green and Tao obtain an extension of well-known Szemeredi's theorem on arithmetic progressions. Their proof of the extension is in spirit of ergodic theory. In the second part, using analytical methods, they reduce a question of existence of progressions in the primes to their extension of Szemeredi's theorem.
In our talk we shall discuss the ergodic part of Green-Tao proof. |

Abstract: |
we discuss the formation of the singularities of the Calabi flow with the assumption of uniform bounded Sobolev constant, in particular on K\"ahler surfaces. On some certain K\"ahler surfaces, we can generalize Tian'c condition to get the Sobolev constant a priori and show there is no bubble formed along the flow. It follows that the convergence of the flow and some new existence result of constant scalar curvature metric on certain K\"ahler class. |

Shear-induced Mixing |
Presenter: |
Lai-Sang Young, Courant Institute, New York University |
Date: |
Monday, October 22, 2007, Time: 4:00 p.m., Location: Fine Hall 214 |
Abstract: |
I will discuss the phenomenon of shear-induced mixing in driven dynamical systems. The unforced system is assumed to have certain simple underlying structures, such as attracting periodic solutions or equilibria undergoing Hopf bifurcations. Specifics of the defining equations are unimportant. A geometric mechanism for producing chaos - or equivalently promoting mixing - is proposed. In the case of periodic kicks followed by long periods of relaxation, rigorous results establishing the presence of strange attractors with SRB measures are presented. These attractors belong in a class of chaotic systems that can be modeled (roughly) by countable-state Markov chains. From this I deduce information on their statistical properties. In the last part of this talk, I will explore numerically the range of validity of the geometric ideas discussed. Examples including stochastically forced coupled oscillators will be presented.

Asset Selection and Under- Diversification with Financial Constraints and Income: Implications for Household Portfolio Studies |
Presenter: |
Stathis Tompaidis, University of Texas at Austin |
Date: |
Tuesday, October 23, 2007, Time: 4:30 p.m., Location: Fine Hall 322 |
Abstract: |
We offer a rational explanation for the observed under-diversification of household porfolios in a complete market, partial equilibrium setting with an investor with CRRA preferences, whose investment opportunity set includes both a riskless asset and multiple risky assets, and who receives an income stream. We show that when the investor faces a margin requirement based on his current wealth, he shifts his portfolio towards undiversified portfolios with fewer assets that offer higher expected returns. We identify the ration of financial wealth to financial wealth augmented by discounted lifetime labor income as the variable that governs the investor's behavior. We also consider the general equilibrium cross-sectional implications of margin requirements in an overlapping-generations model. Joint with Herve Roche. |

Castelnuovo-Mumford regularity and Projections of Algebraic Varieties |
Presenter: |
David Eisenbud, University of California at Berkeley |
Date: |
Wednesday, October 24, 2007, Time: 4:30 p.m., Location: Fine Hall 314 |
Abstract: |
Riemann Surfaces were first studied algebraically by first projecting them into the complex projective plan; later the same idea was applied to surfaces and higher dimensional varieties, projecting them to hypersurfaces. How much damage is done in this process? For example, what can the fibers of a general projection look like? This is pretty easy for smooth curves and surfaces (though there are still open questions), not so easy in the higher-dimensional case. I'll explain some of what's known, including recent work of mine with Roya Beheshti, Joe Harris, and Craig Huneke. |

Functional Sparsity |
Presenter: |
John Lafferty, Computer Science, Carnegie Mellon University |
Date: |
Monday, November 5, 2007, Time: 4:00 p.m., Location: Fine Hall 214 |
Abstract: |
Substantial progress has recently been made on understanding the behavior of sparse linear models in the high dimensional setting, where the number the variables can greatly exceed the number of samples. This problem has attracted the interest of multiple communities, including applied mathematics, signal processing, statistics, and machine learning. But linear models often rely on unrealistically strong assumptions, made more by convenience than conviction. Can we understand the properties of high dimensional nonlinear functions that enable them to be estimated accurately from sparse data? In this talk we present some progress on this problem, showing that many of the recent results for sparse linear models can be extended to the infinite dimensional setting of nonparametric function estimation. In particular, we present some theory for estimating sparse additive models, together with algorithms that are scalable to high dimensions. We illustrate these ideas with an application to functional sparse coding of natural images. This is joint work with Han Liu, Pradeep Ravikumar, and Larry Wasserman. |

Thursday, November 8, 2007, Time: 4:30 p.m., Location: E-219, E-Quad |
Abstract: |
In the first part of the talk, we will present a result showing how one can compute the spot volatility dynamics from the implied volatility surface. Then, we will look at an application to foreign exchange options: we take the exchange rates EURUSD, USDJPY, and EURJPY and reconstruct the implied volatility smile of one exchange rate from the other two. In the third part of the talk, we study the convergence of at-the-money implied volatilities to the spot volatility in a general model with a Brownian component and a jump component of finite variation. This result is a consequence of the robustness of the Black-Scholes formula and of the central limit theorem for martingales. |

Abstract: |
In this joint work with Susan Williams we consider the conjecture: a knot is nonfibered if and only if its infinite cyclic cover has uncountably many finite covers. We prove it for a class of knots that includes all knots of genus 1. We also discuss two equivalent forms of the conjecture, one involving twisted Alexander polynomials, the other a weak form of subgroup separability. |

A Hierarchy of Mathematical Models for Studying the Earth's Climate |
Presenter: |
Dargan Frierson, Atmospheric Sciences, University of Washington |
Date: |
Monday, November 19, 2007, Time: 4:00 p.m., Location: Fine Hall 214 |
Abstract: |
The Earth's climate is a remarkably complex physical system; constructing models to study it is a difficult task which requires parameterization of a multitude of physical processes. Not surprisingly, such models quickly become difficult to understand due to the vast number of nonlinear processes that are active in them. Therefore, an important line of work in atmospheric science involves the development and use of intelligently chosen idealized models, designed to better understand the results of comprehensive climate models as well as the fundamental dynamics of atmospheric circulations. These models are simpler to interpret than the full climate models, but hopefully can still provide insight into the dynamics of their more complex cousins. In this talk, we give a summary of some topical problems in climate dynamics, and the hierarchical modeling approach we have used to study them. We will discuss physical problems such as the predicted poleward shift of the midlatitude jet stream with global warming, and changes in energy fluxes and temperature gradients in the atmosphere. Focusing on the effect of moist convection on these issues, we present a variety of idealized models that we have used to study these problems. These range from models of 3-D fluid motion on a rotating sphere in the presence of condensation, to highly idealized 1-D PDE models of diffusive energy transport. |

Presenter: |
Marsha Berger, Courant Institute, New York University |
Date: |
Monday, December 3, 2007, Time: 4:00 p.m., Location: Fine Hall 214 |
Abstract: |
We discuss some of the steps involved in preparing for and carrying out a fluid flow simulation in complicated geometry. Our goal is to automate this process as much as possible to enable high quality inviscid flow calculations. We use multilevel Cartesian meshes with irregular cells only in the region intersecting a solid object. We present some of the technical issues involved in this approach, including the special discretizations needed to avoid loss of accuracy and stability at irregular boundary cells, as well as how we obtain highly scalable parallel performance. This method is in routine use for aerodynamic calculations in several organizations, including NASA Ames Research Center. Many open problems are discussed. |

A Sharp Compactness Theorem for Genus-One Pseudo-Holomorphic Maps and Applications |
Presenter: |
Aleksey Zinger, Stony-Brook University |
Date: |
Friday, December 7, 2007, Time: 1:30 p.m., Location: Fine Hall 314 |
Abstract: |
Moduli spaces of stable maps are often called ``compactifications" of spaces of maps from smooth domains. In general, however, the latter are not dense in former. For the model target space P^n, the moduli space of genus 0 maps is an honest compactification, but positive genus moduli spaces have components of different dimensions. This seemingly technical point leads to very different and generally poorly understood behavior of positive-genus Gromov-Witten invariants. In this talk I will describe a sharp version of Gromov's compactness theorem for genus-one pseudo-holomorphic maps that leads to much smaller ``compactifications" of spaces of maps from smooth domains. These are sharp in my cases, as well as with respect to being naturally. Applications of this compactness theorem include new genus 1 GW-invariants with geometric properties similar to those of genus 0 GW -invariants, better understanding of the standard genus 1 GW-invariants, a natural smooth compactification of the Hilbert scheme of smooth genus 1 curves in P^n, and the proof of the 1993 BCOV mirror symmetry prediction for genus 1 GW-invariants of a quintic threefold. |

Collective motion and decision-making in animal groups |

Iain Couzin, Ecology & Evolutionary Biology, Princeton University |

Monday, December 10, 2007, Time: 4:00 p.m., Location: Fine Hall 214 |
Abstract: |
Animal groups such as bird flocks, insect swarms and fish schools are spectacular, ecologically important and sometimes devastating features of the biology of various species. Outbreaks of the desert locust, for example, can invade approximately one fifth of the Earth's land surface and are estimated to affect the livelihood of one in ten people on the planet. Using a combined theoretical and experimental approach involving insect and vertebrate groups I will address how, and why, individuals move in unison and investigate the principals of information transfer in these groups, particularly focusing on leadership and collective consensus decision-making.
For very large animal groups, despite huge differences in the size and cognitive abilities of group members, recent models from theoretical physics ('self-propelled particle', SPP, models) have suggested that general principles underlie collective motion. Such models demonstrate that some group-level properties may be largely independent of the types of animals involved. I shall present recent experimental work on locusts that validates some of the predictions of simple mechanistic models including a density-dependent "phase transition" from disordered to ordered motion.
Details of the mechanism by which individuals interact, however, also provide important biological insights into swarm behaviour. Using laboratory studies involving nerve manipulation and field experiments we demonstrate that some swarming insects are in effect on a "forced march" driven by cannibalism.
These results will be discussed in the context of the evolution of functional complexity and pattern formation in biological systems. |
