Abstract

Abstract. Consider a finite group G acting on a vector space V
over a field k of characteristic p > 0. A separating algebra is a
subalgebra A of the ring of invariants k[V]^G with the same point
separation properties. In this article we compare the depth of an
arbitrary separating algebra with that of the corresponding ring of
invariants. We show that, in some special cases, the depth of A is
bounded above by the depth of k[V]^G .
