Algebraic Geometry

 Date:  Wednesday, October 06, 2021 Location:  4096 East Hall (4:15 PM to 5:30 PM) Title:  Purely inseparable Galois theory Abstract:   Given a field $K$ of characteristic $p$, a classical result of Jacobson provides a Galois correspondence between finite purely inseparable subfields of exponent one (those with $K^p\subset L\subset K$), and sub-restricted Lie algebras of $\mathrm{Der}(K)$. I will discuss joint work with Lukas Brantner in which we extend this Galois correspondence to subfields of arbitrary exponent using methods from derived algebraic geometry.
