• ### Algebra Seminar

Monday March 19, 2018 at 13:30, Wachman 617
Introduction to infinite Galois extensions

Vasily Dolgushev, Temple University

This series of lectures will be devoted to infinite Galois extensions and I plan to follow Chapter 7 of Milne's book "Fields and Galois Theory". In this talk, I will give a brief reminder of topological groups and introduce the Krull topology on the Galois group.

• ### Analysis Seminar

Monday March 19, 2018 at 14:40, Wachman 617

Andy Raich, University of Arkansas

The main goal of this talk is to show that geometric information captured by certain invariant CR tensors provides sufficient information to establish the closed range property for $\bar\partial$ on a domain in $\mathbb{C}^n$. A secondary goal of the talk is to provide a general construction method for establishing when a domain (or its boundary) satisfies weak $Z(q)$.

• ### Colloquium

The relation (X+Y)^n = X^n + Y^n, and miraculous cancellations in quantum SL_2

Francis Bonahon, USC

The convenient formula (X+Y)^n = X^n + Y^n is (unfortunately) frequently used by our calculus students. Our more advanced students know that this relation does hold in some special cases, for instance in prime characteristic n or when YX=qXY with q a primitive n-root of unity. I will discuss similar miraculous cancellations’’ for 2-by-2 matrices, in the context of the quantum group U_q(sl_2).

• ### Geometry and Topology Seminar

Wednesday March 21, 2018 at 14:30, Wachman 617
Genus bounds in right-angled Artin groups

Jing Tao, University of Oklahoma

Abstract: In this talk, I will describe an elementary and topological argument that gives bounds for the stable commutator lengths in right-angled Artin groups.
