Abstract
Let R be a commutative Noetherian ring of prime characteristic p. The main goal of this paper is to study in some detail when (Formula presented.) is an open set in the Zariski topology, where FEp denotes the Frobenius algebra attached to the injective hull of the residue field of Rp. We show that this is true when R is a Stanley–Reisner ring; moreover, in this case, we explicitly compute its closed complement, providing an algorithmic method for doing so.
