Title: Lyubeznik numbers
Abstract: Lyubeznik numbers are certain Bass numbers of local cohomology
modules associated with local rings containing a field. These numerical
invariants are known to have many interesting homological, geometric, and
topological properties and have been an active area of research. In this
talk, we plan to give a brief overview of these.
