DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FOTR/3/">Two
  applications of $p$-derivations to commutative algebra</a>\nby Jack Jeffr
 ies (CIMAT) as part of Fellowship of the Ring\n\n\nAbstract\nThe notions o
 f derivations and modules of differentials have been central in commutativ
 e algebra for much of its history. A somewhat more exotic notion is that o
 f $p$-derivations: these are maps that satisfy functional equations simila
 rly to derivations\, but are not even additive. Nonetheless\, $$-derivatio
 ns and related constructions have found applications in arithmetic geometr
 y. In this talk\, we will give a basic introduction to p-derivations\, and
  discuss two applications to commutative algebra\, based on projects with 
 Melvin Hochster and Anurag K. Singh (each).\n
