Speaker: Florian Enescu Title: Lower bounds for Hilbert-Kunz multiplicities Abstract: We will present various lower bounds for Hilbert-Kunz multiplicities of local rings in terms of numerical invariants such as Hilbert-Samuel multiplicities, type, embedding dimension. We will discuss the implications of these bounds of the conjecture that the Hilbert-Kunz mulplicity of a local non-regular ring is bounded by below by a number strictly greater than 1 depending only on the dimension of the ring. This joint work with Ian M. Aberbach.
