Abstract

In this work we define a numerical invariant called FF-volume. This number extends the definition of FF-threshold of a pair of ideals II and JJ, cJ(I)c^J(I) to a sequence of ideals JJ, I1,,ItI_1, \ldots, I_t. We obtain several properties that emulate those of the FF-threshold. In particular, the FF-volume detects FF-pure complete intersections. In addition, we relate this invariant to the Hilbert-Kunz multiplicity.
