Descent, Derivations, and the Jacobson-Bourbaki Theorem
Abstract: We start with some basic theory on derivations of rings and extensions of derivations, then will see how derivations over fields and the more classical Galois theory can be seen as examples of the Jacobson-Bourbaki Theorem. We end by connecting this theorem into Grothendieck's ideas for faithfully flat descent. This is a make-up talk from the snow day.
