SUMMARY:A theory of the b-function in positive characteristic - Thomas B
 itoun (Oxford)

DESCRIPTION:Building on earlier work of Mustata\, we present a constructio
 n in noncommutative nonnoetherian algebra that should be understood as a p
 ositive characteristic analogue of the b-function. Recall that the b-fun
 ction or Bernstein-Sato polynomial is a polynomial in one variable attach
 ed to an analytic function f. It is a fundamental object in D-module the
 ory and is well-known to be related to the singularities of f. We will st
 art by briefly recalling the complex theory. \n
