# Events for September 29, 2017 from General and Seminar calendars

## Mathematical Physics and Harmonic Analysis Seminar

## Several Complex Variables Seminar

## Algebra and Combinatorics Seminar

**Abstract:** Some questions about deformations of algebras can be answered by using Hochschild cohomology, and in particular by using its Lie/Gerstenhaber brackets. Until very recently there was no independent description of this Lie structure for an arbitrary resolution, a big disadvantage both theoretically and computationally. In this talk, we will first introduce Hochschild cohomology and explain its role in algebraic deformation theory. We will then summarize recent progress by several mathematicians, focusing on examples.
