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. |
