Lie algebras, deformations, and Galois theory in characteristic p.

HARVARD-MIT ALGEBRAIC GEOMETRY

Speaker:

Lukas Brantner

We introduce a derived version of Lie algebras in characteric p and describe two recent applications: first, we use them to classify infinitesimal deformations, generalising the Lurie-Pridham theorem in characteristic zero; second, we prove a Galois correspondence for purely inseparable field extension, extending work of Jacobson at height one. This talk is based on joint works with Mathew and Waldron.
