##### Global regularity for 2d water waves
###### Analysis Seminar

We consider the water waves system for the evolution of a perfect irrotational fluid with a free boundary, in 2 spatial dimensions, under the influence of gravity. We prove the existence of global solutions for suitably small and regular initial data. We also prove that the asymptotic behavior of solutions as time goes to infinity is different from linear, unlike the 3 dimensional case.

##### H\"older estimates for fully nonlinear parabolic integro-differential equations
###### Differential Geometry & Geometric Analysis Seminar

Please note special day, time and location.  We will revisit H\"older estimates for some non local problems we worked recently with G. D\'avila. They arise in stochastic optimal control

##### An infinite rank summand of topologically slice knots
###### Topology Seminar

Let C_{TS} be the subgroup of the smooth knot concordance group generated by topologically slice knots. Endo showed that C_{TS} contains an infinite rank subgroup, and Livingston and Manolescu-Owens showed that C_{TS} contains a Z^3summand. We show that in fact C_{TS} contains a Z^\infty summand.

##### Complex analytic vanishing cycles for formal schemes
###### Princeton University/IAS Number Theory Seminar

Let $R={\cal O}_{{\bf C},0}$ be the ring of power series convergent in a neighborhood of zero in the complex plane. Every scheme $\cal X$ of finite type over $R$ defines a complex analytic space ${\cal X}^h$ over an open disc $D$ of small radius with center at zero.

##### Recent progress in distinct distances problems
###### Discrete Mathematics Seminar

PLEASE CLICK ON SEMINAR TITLE FOR COMPLETE ABSTRACT. During 2013, significant progress has been made on several problems that are related to the Erdos distinct distances problem. In this talk I plan to briefly describe some of these results and the tools that they rely on. I will focus on the following two results.

##### Lagrangian submanifolds of complex projective space
###### Symplectic Geometry Seminar

First, I will discuss a proof that a Lagrangian torus in ℂℙ2 arising from a semitoric system described by Weiwei Wu coincides with the image in ℂℙ2 of Chekanov's exotic Lagrangian torus in ℝ4.

##### On the singularities of the Szego projections on CR manifolds
###### Differential Geometry & Geometric Analysis Seminar

In this talk, I will report the first part of my paper(Projections  in several complex variables, Mem. Soc. Math. France, 2010, 131 p.). In this work, we completely study the heat equation method of Menikoff-Sjostrand and  apply it to the Kohn Laplacian defined on a compact orientable connected CR manifold.

##### Fast Direct Solvers for Elliptic PDEs
###### PACM/Applied Mathematics Colloquium

That the linear systems arising upon the discretization of elliptic PDEs can be solved very efficiently is well-known, and many successful iterative solvers with linear complexity have been constructed (multigrid, Krylov methods, etc).
