Factorisation Algebras in Quantum Field Theory and Arithmetic Geometry

Organisers: Clark Barwick, Owen Gwilliam, Minhyong Kim 

This is an online working seminar in the winter/spring of 2026 on the topics of the title. We will meet on Thursdays at 2PM UK starting on 19 February.

Clark Barwick will start out explaining the ideas of his new preprint. More details and references will be added as the seminar progresses.

The following ideas will be discussed eventually:

--BV formalism and arithmetic QFTs

--Arithmetic non-linear sigma models

--QFT and Langlands duality

and more
