Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Quantitative Floer Theory and Coefficients
Yusuke Kawamoto
9:15am|Remote Access

I will discuss how much the choice of coefficients impacts the quantitative information of Floer theory, especially spectral invariants. In particular, I will present some phenomena that are specific to integer coefficients, including an answer to a...

Joint PU/IAS Number Theory

Moments of Quadratic L-Functions Over Function Fields
Adrian Diaconu
4:30pm|*Princeton University, Fine 214*

In 2001, Conrey, Farmer, Keating, Rubinstein, and Snaith developed a "recipe" utilizing heuristic arguments to predict the asymptotics of moments of various families of L-functions. This heuristic was later extended by Andrade and Keating to include...

Special Year Workshop on p-adic Arithmetic Geometry

The Analytic Topology Suffices for the B_dR^+-Grassmannian
Kęstutis Česnavičius
2:00pm|Wolfensohn Hall

Abstract: For a reductive group $G$, its $B_{d}R^{+}$-affine Grassmannian is defined as the étale (equivalently, v-) sheafification of the presheaf quotient $LG/L^{+}G$ of the $B_{d}R$-loop group $LG$ by the $B_{d}R^{+}$-loop subgroup $L^{+}G$. We...

Some Vanishing Results for Rational Completed Cohomology of Shimura Varieties
Lue Pan
11:45am|Wolfensohn Hall

Abstract: Let p be a prime number. Emerton introduced the p-adically completed cohomology, which admits a representation of some p-adic group and can be thought of as some spaces of p-adic automorphic forms. In this talk, I want to explain that for...

Duality Theorems for p-adic Pro-Étale Cohomology of Stein Spaces
Wieslawa Niziol
10:00am|Wolfensohn Hall

Abstract: I will discuss the formulation and sketch the proofs of duality theorems for the geometric and arithmetic p-adic pro-étale cohomology of Stein spaces. This is based on a joint work with Pierre Colmez and Sally Gilles.

Mathematical Conversations

Equivariant Log-Concavity and the Hard Lefschetz Theorem
6:00pm|Birch Garden, Simons Hall

What do graph matchings and independent vertex sets have to do with the cohomology of products of projective lines? I will share with you an example in the study of “equivariant log-concavity”, which enriches the notion of log-concavity. By keeping...

A Kirillov Model for Completed Cohomology
Pierre Colmez
12:00pm|Wolfensohn Hall

Abstract: We will explain how to construct a Kirillov model for Emerton's completed cohomology of the tower of modular curves. The trickiest part is to prove injectivity of this model.  This is joint work with Shanwen Wang.

Special Year Workshop on p-adic Arithmetic Geometry

p-adic Analytic Geometry and Chromatic Homotopy Theory
Tomer Schlank
4:30pm|Wolfensohn Hall

Abstract: Chromatic homotopy theory relates certain important questions in homotopy theory to the theory of formal groups. 

Recent advancements in p-adic geometry can be thus used to study questions in homotopy theory. I will discuss how this...

Special Year Workshop on p-adic Arithmetic Geometry

Prismatic Crystals, q-Higgs Modules, and their Cohomology
Takeshi Tsuji
2:30pm|Wolfensohn Hall

Abstract: We study prismatic crystals and their cohomology by using q-Higgs modules (= a q-analogue of p-connections). When the base is lying over the q-crystalline prism, they are locally described in terms of q-Higgs modules and the associated...
