# Math Science Lectures in Honor of Raoul Bott

CMSA EVENTS

##### Speaker:

Michael Freedman *- Microsoft*

On **October 4th** and **October 5th**, 2021, Harvard CMSA will host its annual Math Science Lectures in Honor of Raoul Bott. This year’s speaker will be Michael Freedman (Microsoft). The lectures will take place from **11:00am – 12:15pm** (ET) on Zoom.

**You must register to attend. Register here.**

This will be the third annual lecture series held in honor of Raoul Bott.

Lecture 1:

**Monday, October 4, 11:00 am - 12:15 pm ET**

**Title**: The Universe from a single Particle

**Abstract**: I will explore a toy model for our universe in which spontaneous symmetry breaking – acting on the level of operators (not states) – can produce the interacting physics we see about us from the simpler, single particle, quantum mechanics we study as undergraduates. Based on joint work with Modj Shokrian Zini, see **arXiv:2011.05917** and **arXiv:2108.12709**** **

Lecture 2:

**Tuesday, October 5, 11 am - 12:15 pm ET**

**Title**: Controlled Mather Thurston Theorems.

**Abstract**: The “c-principle” is a cousin of Gromov’s h-principle in which cobordism rather than homotopy is required to (canonically) solve a problem. We show that in certain well-known c-principle contexts only the mildest cobordisms, semi-s-cobordisms, are required. In physical applications, the extra topology (a perfect fundamental group) these cobordisms introduce could easily be hidden in the UV. This leads to a proposal to recast gauge theories such as EM and the standard model in terms of flat connections rather than curvature. See **arXiv:2006.00374**** **
