Title: "Nonsmooth Lojasiewicz inequalities"

Abstract: Consider a real-analytic function f on a Euclidean space, and suppose f(0)=0. The Lojasiewicz gradient inequality asserts the existence of a positive exponent a<1 such that


is bounded above near 0. It is a crucial tool in a recent proof of the famous "gradient conjecture of Thom", that steepest descent trajectories for real-analytic functions do not oscillate near critical points. I will outline some nonsmooth variants. This is joint work with Jerome Bolte and Aris Daniilidis.
