1:30PM  3:30PM: Two applications of pderivations to commutative algebraJack JeffriesLocation: Online via ZoomThe notions of derivations and modules of differentials have been central in commutative algebra for much of its history. A somewhat more exotic notion is that of pderivations: these are maps that satisfy functional equations similarly to derivations, but are not even additive. Nonetheless, pderivations and related constructions have found applications in arithmetic geometry. In this talk, we will give a basic introduction to pderivations, and discuss two applications to commutative algebra, based on projects with Melvin Hochster and Anurag K. Singh (each).
