Noncommutative Geometry

Speaker: (Western)

"Maurer-Cartan forms and odd Chern character"

Time: 11:30

Room: MC 107

In this talk, we shall exhibit explicit formulas for the odd Chern character map.

Homotopy Theory

Speaker: Chris Kapulkin (Western)

"Properties of the Identity Type (part 1)"

Time: 13:30

Room: MC 107

Following Chapter 2 of the HoTT Book, I will present the main properties of the Identity Type.

Analysis Seminar

Speaker: Purvi Gupta (Western)

"Some new analogies between convex and complex analysis - Part II"

Time: 15:30

Room: MC 107

We will discuss the convex floating body method of extending Blaschke's affine surface area measure to all convex bodies. We will then introduce the Fefferman hypersurface area measure on the boundary of a strongly pseudoconvex domain. This measure transforms well under biholomorphisms, and we will discuss why this can be useful. Taking tube domains as the motivating case, we will propose a method for extending this measure to general pseudoconvex domains.

Basic Notions Seminar

Speaker: Rick Jardine (Western)

"What is a ring spectrum?"

Time: 15:30

Room: MC 107

This talk is a leisurely introduction to spectra, symmetric spectra and cup products in stable homotopy theory. Ring spectra are discussed as examples, in various contexts.
