# Hayden Howard Lecture

## The 2017-18 Hayden-Howard lecture

**Speaker**: Mike Hill, Department of Mathematics, UCLA**Time and location**: Monday, 9 April 2018, 4pm. 214 Whitehall Classroom Building**Title:** Evenness in algebraic topology

**Abstract:** There are several different notions of what it might mean for a space to be "even" in algebraic topology, all of which have useful, increasingly algebraic properties. I will begin by describing some classical work due to Wilson, focusing on what sorts of things happen when we have only even cells or homotopy groups, and then I will describe more recent work (all joint with Hopkins), where building on geometric intuition, we construct a version of this that works also when there is an action of a finite group.

### About the Hayden-Howard lecture

The Hayden-Howard lecture was inaugurated in the spring of 2001 by a generous contribution from a friend of the Department of Mathematics. The lecture series was established in honor of mathematics professors Thomas Hayden and Henry Howard. Each year, the lecture series brings a research mathematician of international stature to the University of Kentucky.
