Joint IAS/Princeton University Number Theory Seminar

Local (\ell = p) Galois Deformation Rings
Ashwin Iyengar
4:30pm|Simonyi Hall 101 and Remote Access

I will present joint work with V. Paškūnas and G. Böckle concerning deformation rings for mod $p$ Galois representations of $p$-adic local fields. After giving a short introduction to the subject, I will explain our main result which says that...

Arithmetic Groups

From $PSL_2$ representation rigidity to profinite rigidity
Alan Reid and Ben McReynolds
11:00am|Simonyi 101 and Remote Access

In the first part of this talk, we take the ideas of the second talk and focus on the case of (arithmetic) lattices in $PSL(2,R)$ and $PSL(2,C)$. The required representation rigidity is achieved by what we call Galois rigidity. In particular if $...

Seminar in Analysis and Geometry

Totally nonparallel immersions
Michael Harrison
2:00pm|Simonyi Hall 101 and Remote Access

An immersion from a smooth n-dimensional manifold $M$ into $R^q$ is called totally nonparallel if, for every pair of distinct points $x$ and $y$ in $M$, the tangent spaces at $f(x)$ and $f(y)$ contain no parallel lines. The simplest example is the...

Members' Colloquium

PDEs vs. Geometry: analytic characterizations of geometric properties of sets
Svitlana Mayboroda
2:00pm|Simonyi Hall 101 and Remote Access

In this talk we will discuss connections between the geometric and analytic/PDE properties of sets. The emphasis is on quantifiable, global results which yield true equivalence between the geometric and PDE notions in very rough scenarios, including...
