Abstract

Bernstein's inequality is a fundamental result in the theory of D-modules on smooth varieties, with many important consequences. However, rings of differential operators are much more poorly behaved on singular varieties in general. In this talk we will discuss a version of Bernstein's inequality that holds on certain singular singularities. This is based on joint work with Josep Àlvarez Montaner, Daniel J. Hernández, Luis Núñez-Betancourt, Pedro Teixeira, and Emily E. Witt.
