The Surface Subgroup Theorem and the Ehrenpreis conjecture |
| Presenter: |

| Abstract: |
We prove that there is a hyperbolic surface S such that for any closed hy- perbolic 2 or 3-manifold M, and > 0, there is a nite cover ^ S of S, and a map f: ^ S ! M that is locally within of being an isometric immersion. When dimM = 3 this implies that 1(M) has a surface subgroup, and when dimM = 2 this is the Ehrenpreis conjecture. In either case, the surface f(S) is constructed by putting together immersed pairs of pants in M, and in both cases we can construct a collection of good pants that are evenly distributed around every closed geodesic that appears as a boundary. If dimM = 3 then we can immediately assemble these pants, with a twist, to form the desired surface f(S). In the case where dimM = 2, there may be more pants on one side of a geodesic than the other. In order to determine how to correct the collection of pants, we develop the \good pants homology" of good curves modulo the boundaries of good pants, and show through a series of algebraic identities that it is equivalent to the standard homology. This is joint work with Vladimir Markovic. 1 |

| Abstract: |
Let Gamma be a non-elementary discrete geometrically finite subgroup of PSL(2,C). Under the assumption that the critical exponent of Gamma is greater than 1 we prove an effective bisector counting theorem for Gamma. We then apply this Theorem to the Apollonian circle packing problem to get power savings and to compute the overall constant. The proof relies on spectral theory of Gamma\PSL(2,C). |

Pareto Optimal Solutions for Smoothed Analysts |

| Abstract: |
Consider an optimization problem with n binary variables and d+1 linear objective functions. Each valid solution in {0,1}^n gives rise to an objective vector in R^{d+1}, and one often wants to enumerate the Pareto optima among them. In the worst case there may be exponentially many Pareto optima; however, it was recently shown that in (a generalization of) the smoothed analysis framework, the expected number is polynomial in n (Roeglin, Teng, FOCS 2009). Unfortunately, the bound obtained had a rather bad dependence on d; roughly n^{d^d}. In this paper we show a significantly improved bound of n^{2d}. Our proof is based on analyzing two algorithms. The first algorithm, on input a Pareto optimal x, outputs a "testimony" containing clues about x's objective vector, x's coordinates, and the region of space B in which x's objective vector lies. The second algorithm can be regarded as a SPECULATIVE execution of the first -- it can uniquely reconstruct x from the testimony's clues and just SOME of the probability space's outcomes. The remainder of the probability space's outcomes are just enough to bound the probability that x's objective vector falls into the region B. This is joint work with Ryan O'Donnell. |

I will discuss Z/2-equivariant motivic spectra. As an example, I will talk about a Z/2-equivariant motivic spectrum representing Karoubi's Hermitian K-theory, and my joint solution with Kriz and Ormsby of Thomason's homotopy limit problem. As another example, I will talk about motivic Hermitian cobordism, and its topological realization, topological Hermitian cobordism. This is an RO(G)-graded (Z/2 \times Z/2)-equivariant spectrum, whose RO(G)-graded homotopy groups we have computed. |

| Abstract: |
A conjecture of Langlands-Rapoport predicts the structure of the mod p points on a Shimura variety. The conjecture forms part of Langlands' program to understand the zeta function of a Shimura variety in terms of automorphic L-functions. I will report on progress towards the conjecture in the case of Shimura varieties attached to non-exceptional groups. |

| Abstract: |
After reviewing the proof of the Riemannian positive mass theorem in dimensions less than 8, I will briefly explain how to generalize the proof to slices of spacetime that are not time- symmetric. The basic idea is to replace minimal hypersurfaces by marginally outer-trapped hypersurfaces, and the main difficulty is to avoid using any minimization process. This is joint work with Eichmair, Huang, and Schoen. |

| Abstract: |
A classical problem in geometric combinatorics is to determine how often a single distance may repeat among $n$ points in the plane. A related problem that has received much attention is how often a given triangle can repeat among $n$ points in the plane. We shall report on some partial progress on the second problem using a continuous analog, proved via a Sobolev estimate for a bilinear averaging operator and a conversion mechanism that allows us to deduce a discrete result from a sufficiently robust continuous analog. |

We will discuss recent work on the energy critical wave equation. The issues studied are global existence, scattering, finite time blow-up, universal profiles at blow-up and soliton resolution. This is viewed not as an isolated series of results, but as a way of approaching many similar critical non-linear dispersive equations. |

Noncollision singularities in planar two-center-two-body problem |
| Presenter: |
Jinxin Xue, IAS |
| Date: |
Thursday, March 15, 2012, Time: 2:00 p.m., Location: Fine Hall 601 |
| Abstract: |
In this work we study a model called planar 2-center-2-body problem. In the plane, we have two fixed centers Q_1=(-\chi,0), Q_2=(0,0) of masses 1, and two moving bodies Q_3 and Q_4 of masses \mu. They interact via Newtonian potential. Q_3 is captured by Q_2, and Q_4 travels back and forth between two centers. Based on a construction of Gerver, we prove that there is a Cantor set of initial conditions which lead to solutions of the Hamiltonian system whose velocities are accelerated to infinity within finite time avoiding all early collisions. We consider this model as a simplified model for the planar four-body problem case of the Painleve conjecture. This is a joint work with Dmity Dolgopyat. |

| Abstract: |
Identifiable regions of high connectivity in a matroid or graph are captured by the notion of ``tangles''. For a tangle of order k in a matroid or graph that satisfies a certain robustness condition, we describe a tree decomposition of the matroid or graph that displays, up to a certain natural equivalence, all of the k-separations of the matroid or graph that are non-trivial with respect to the tangle. This is joint work with Geoff Whittle. |

A Khovanov homotopy type |
| Presenter: |
Sucharit Sarkar, Columbia University |
| Date: |
Thursday, March 15, 2012, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: |
We will start by describing Khovanov's categorification of the Jones polynomial from a cube of resolutions of a link diagram. We will then introduce the notion of a framed flow category, as defined by Cohen, Jones and Segal. We will see how a cube of resolutions produces a framed flow category for the Khovanov chain complex, and how the framed flow category produces a space whose reduced cohomology is the Khovanov homology. We will show that the stable homotopy type of the space is a link invariant. Time permitting, we will show that the space is often non-trivial, i.e., not a wedge sum of Moore spaces. This work is joint with Robert Lipshitz. |

L^p bounds for eigenfunctions on locally symmetric spaces |
| Presenter: |
Simon Marshall, Northwestern University |
| Date: |
Friday, March 16, 2012, Time: 3:00 p.m., Location: Fine Hall 314 |
| Abstract: |
There is a classical theorem of Sogge which provides bounds for the L^p norms of a Laplace eigenfunction on a compact Riemannian manifold, which are sharp on the sphere and for spectral clusters. I will present a generalization of this theorem to eigenfunctions of the full ring of invariant differential operators on a locally symmetric space, as well as a theorem on the restriction of eigenfunctions to maximal flat subspaces. Time permitting, I will discuss ways in which these bounds can be improved using inputs from number theory. |

Local smoothing and Strichartz estimates for manifolds with degenerate hyperbolic trapping |
| Presenter: |
Hans Cristianson, University of North Carolina at Chapel Hill |
| Date: |
Monday, March 26, 2012, Time: 3:15 p.m., Location: Fine Hall 314 |
| Abstract: |
It is well known that on $\reals^n$, the Schrödinger propagator is unitary on $L2$ based spaces, but that locally in space and on average in time there is a $1/2$ derivative smoothing effect. We consider a family of manifolds with trapped geodesics which are degenerately hyperbolic and prove a sharp local smoothing estimate with loss depending on the type of trapping. Further, we construct a microlocal parametrix extended polynomially beyond Ehrenfest time, and as a consequence, we obtain Strichartz estimates with near-sharp loss depending only on the dimension of the trapping. This is partly joint work with J. Wunsch (Northwestern) |

Geometry and Topology in Dimension Reduction |
| Presenter: |
Sayan Mukherjee, Duke University |
| Date: |
Monday, March 26, 2012, Time: 4:30 p.m., Location: Fine Hall 214 |
| Abstract: |
In the first part of the talk we describe how learning the gradient of a regression function can be used for supervised dimension reduction (SDR). We provide an algorithm for learning gradients in high-dimensional data, provide theoretical guarantees for the algorithm, and provide a statistical interpretation. Comparisons to other methods on real and simulated data are presented. In the second part of the talk we present preliminary results on using the Laplacian on forms for dimension reduction. This involves understanding higher-order versions of the isoperimetric inequality for both manfifolds and abstract simplicial complexes. |

The integral Hodge conjecture for 3-folds |

Burt Totaro DPMMS, Cambridge University |
| Date: |
Tuesday, March 27, 2012, Time: 4:30 p.m., Location: Fine Hall 322 |
| Abstract: |
The Hodge conjecture predicts which rational homology classes on a smooth complex projective variety can be represented by linear combinations of complex subvarieties. In other words, it is about the difference between topology and algebraic geometry. The integral Hodge conjecture, the analogous conjecture for integral homology classes, is false in general. We discuss negative results and some new positive results on the integral Hodge conjecture for 3-folds |

| Abstract: |
The classical Hardy-Littlewood-Sobolev inequality implies Sobolev and other geometric inequalities and has a great impact to geometric analysis. Recent results on Sobolev inequalities with negative power indicate the existence of certain extensions to the classical HLS inequality. In this talk, we shall reveal one extension. The existence of sharp constant, as well as the classification of certain extremal functions via the method of moving sphere are also obtained. This is a joint work with J. Dou. |

We consider the cubic defocusing nonlinear Schrodinger equation in the two dimensional torus. Fix s>1. Colliander, Keel, Staffilani, Tao and Takaoka (2010) proved existence of solutions with s-Sobolev norm growing in time by any given factor R. Refining their methods in several aspects we find solutions with s-Sobolev norm growing in polynomial time in R. This is a joint work with V. Kaloshin. |

On Kolmogorov's conjecture and Hausdorff dimension of oscillatory motions for certain restricted three body problems |
| Presenter: |
V. Kaloshin, University of Maryland - College Park |
| Date: |
Wednesday, April 18, 2012, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: |
Consider the classical Newtonian 3-body problem, namely, bodies are mutually attracted by the Newton graviation. Call motion oscillatory if as time tends to infinity limsup of maximal distance among the bodies is infinite, while liminf is finite. In the 50's Sitnikov presented the first rigorous example of ocsillatory motions for the so-called restricted 3-body problem. Later in the 60's Alexeev extended this example to the full 3-body problem. A long-standing conjecture of Kolmogorov is that oscillatory motions have measure zero. We show that for the Sitnikov example and for the so-called restricted planar circular 3-body problem these motions often form a set of maximal possible Hausdorff dimension. This is a joint work with A. Gorodetski. |

The Cauchy problem for the Benjamin-Ono equation in L^2 revisited (Joint work with Luc Molinet) |

Didier Pilod, Universidade Federal do Rio de Janeiro / University of Chicago |
| Date: |
Monday, April 30, 2012, Time: 3:15 p.m., Location: Fine Hall 314 |
| Abstract: |
The Benjamin-Ono equation models the unidirectional evolution of weakly nonlinear dispersive internal long waves at the interface of a two-layer system, one being in finitely deep. The Cauchy problem associated to this equation presents interesting mathematical difficulties and has been extensively studied in the recent years. In a recent work (2007), Ionescu and Kenig proved well-posedness for real-valued initial data in L^2(R). In this talk, we will give another proof of Ionescu and Kenig's result, which moreover provides stronger uniqueness results. In particular, we prove unconditional well-posedness in H^s(R), for s > 1/4 . Note that our approach also permits to simplify the proof of the global well-posedness in L^2(T) by Molinet (2008) and yields unconditional well-posedness in H^{1/2}(T). Finally, it is worthwhile to mention that our technique of proof also apply for a higher-order Benjamin-Ono equation. We prove that the associated Cauchy problem is globally well-posed in the energy space H^1(R). |
