Raul Epure, Delphine Pol: On constructions of free singularities, 35-48


The purpose of this paper is to give new examples of families of free singularities. We first show that a generic equidimensional subspace arrangement is free. Furthermore, we show that a product of two reduced Cohen-Macaulay subspaces is free if and only if both subspaces are free.

Key Words: Freeness, subspace arrangements, logarithmic vector fields.
