Notes

Expository writing

• In September 2020, I gave a weeklong lecture series at the London Mathematical Society Autumn Algebra School titled "Infinite-dimensional Lie algebras and their multivariable generalizations". I prepared a version of my lecture notes for publication in the Lecture Series in Mathematics book series, to be published by Cambridge University Press. These notes can be found here.

Notes from seminar talks

• These slides are from a talk I gave at UoE about a mathematical formulation of type I / heterotic string duality from the point of view of the topological string. (I also gave a pretalk introducing some aspects of the topological string following the work of Kevin Costello and Si Li.)

Other talks

• Some talks about vertex algebras and factorization algebras from a working seminar at UoE.

1. Kac--Moody and Virasoro vertex algebras

2. The Costello--Gwilliam approach to vertex algebras

3. CDO and CDR vertex algebras
