Reductions of Galois representations of small slopes
Eknath Ghate
4:30pm|S-101

We investigate the shape of the reduction of certain crystalline Galois representations of integral slope 1 and of fractional slopes in (1,2). The proof uses the compatibility between the p-adic and mod p Local Langlands Correspondences with respect...

Mini-Symposium on Topology

Is the abstract mathematics of topology applicable to the real world?
Robert D. MacPherson; Randall D. Kamien; Raúl Rabadán
5:30pm|Wolfensohn Hall

Topology is the only major branch of modern mathematics that wasn't anticipated by the ancient mathematicians. Throughout most of its history, topology has been regarded as strictly abstract mathematics, without applications. However, illustrating...

Periodic symplectic cohomologies
1:30pm|S-101

Periodic cyclic homology group associated to a mixed complex was introduced by Goodwillie. In this talk, I will explain how to apply this construction to the symplectic cochain complex of a Liouville domain and obtain two periodic symplectic...

Uniform bounds for the number of rational points on curves of small Mordell-Weil rank
Michael Stoll
4:30pm|Fine 214, Princeton University

We show that there is a bound $N(d,g,r)$ for the number of $K$-rational points on hyperelliptic curves $C$ of genus $g$ when the degree of the number field $K$ is $d$ and the Mordell-Weil rank $r$ of the Jacobian of $C$ is at most $g - 3$. The proof...

Topology of Algebraic Varieties

Derived categories of cyclic covers and their branch divisors
11:15am|S-101

Given a variety $Y$ with a rectangular Lefschetz decomposition of its derived category, I will discuss an interesting relation between the derived categories of a cyclic cover of $Y$ and its branch divisor. As examples, I will describe the cases of...

Extensions of the Gross-Zagier formula
4:30pm|S-101

I will first discuss the general conjectural picture relating algebraic cycles to L-functions and some extensions of the Gross-Zagier formula involving $p$-adic L-functions. This leads naturally to the question of constructing algebraic cycles...
