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 1October 4th, 11:00am (Boston time) | Title: The Universe from a single ParticleAbstract: 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 2October 5th, 11:00am (Boston time) | 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 |
