A converse theorem of Gross-Zagier and Kolyvagin: CM case
4:30pm|S-101

Let $E$ be a CM elliptic curves over rationals and $p$ an odd prime ordinary for $E$. If the $\mathbb Z_p$ corank of $p^\infty$ Selmer group for $E$ equals one, then we show that the analytic rank of $E$ also equals one. This is joint work with...

Quasi-periodic solutions to nonlinear PDE's
11:00am|S-101

We present a new approach to the existence of time quasi-periodic solutions to nonlinear PDE's. It is based on the method of Anderson localization, harmonic analysis and algebraic analysis. This can be viewed as an infinite dimensional analogue of a...

Mathematical Conversations

How deep is your proof?
6:00pm|Dilworth Room

There is a very short proof that a graph is 3-colorable: you simply give the coloring - it is linear in the size of the graph. How long a proof is needed that a given graph is *not* 3-colorable? The best we know is exponential in the size of the...

Nematic liquid crystal phase in a system of interacting dimers
2:00pm|S-101

In 1979, O. Heilmann and E.H. Lieb introduced an interacting dimer model with the goal of proving the emergence of a nematic liquid crystal phase in it. In such a phase, dimers spontaneously align, but there is no long range translational order...

Elliptic curves of rank two and generalised Kato classes
Francesc Castella
4:45pm|S-101

The generalised Kato classes of Darmon-Rotger arise as $p$-adic limits of diagonal cycles on triple products of modular curves, and in some cases, they are predicted to have a bearing on the arithmetic of elliptic curves over $Q$ of rank two. In...

Motivic correlators and locally symmetric spaces II
1:45pm|S-101

According to Langlands, pure motives are related to a certain class of automorphic representations.Can one see mixed motives in the automorphic set-up? For examples, can one see periods of mixed motives in entirely automorphic terms? The goal of...

Computer Science/Discrete Mathematics Seminar II

On the strength of comparison queries
10:30am

Joint work with Daniel Kane (UCSD) and Shachar Lovett (UCSD)We construct near optimal linear decision trees for a variety of decision problems in combinatorics and discrete geometry.For example, for any constant $k$, we construct linear decision...

Cohomology of arithmetic groups and Eisenstein series - an introduction
10:00am|Physics Library, Bloomberg Hall 201

I intend to cover some basic questions and material regarding the phenomena in the cohomology of an arithmetic group "at infinity" when the corresponding locally symmetric space originating with an algebraic $k$-group $G$ of positive $k$-rank is non...

Wrapped Fukaya categories and functors
Yuan Gao
4:00pm|S-101

Inspired by homological mirror symmetry for non-compact manifolds, one wonders what functorial properties wrapped Fukaya categories have as mirror to those for the derived categories of the mirror varieties, and also whether homological mirror...
