Abstract

The purpose of the paper is to introduce a notion of logarithmic differential forms on singular varieties. We also compute the Poincaré series and generators of the corresponding modules in a few particular cases, including quasihomogeneous complete intersections, normal varieties, determinantal varieties, and others.

Keywords
