Harvard–MIT Algebraic Geometry Seminar: On the D-module of an isolated singularity

SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY

Speaker:

Thomas Bitoun - University of Calgary

Let Z be the germ of a complex hypersurface isolated singularity of equation f. We consider the family of analytic D-modules generated by the powers of 1/f and relate it to the pole order filtration on the de Rham cohomology of the complement of \{f=0\}. This work builds on Vilonen’s characterization of the intersection homology D-module.
