Fo r a finite group acting linearly on a vector space\, a separating set is simply a set of invariants whose elements separate the orbits o the acti on. Such a set need not generate the ring of invariants. In this talk\, w e give lower bounds on the size of separating sets based on the geometry of the action. These results are obtained via the study of the local coho mology with support at an arrangement of linear subspaces naturally arisi ng from the action.(Joint with Jack Jeffries) X-ALT-DESC: The study of separating invariants is a new trend in Invariant Theory and a return to its roots: invariants as a classification tool.
