Title: Title: Tensor decomposition, geometry, and matrix multiplication

Abstract: I will explain several uses of geometric methods in the study of problems originating in computer science, numerical analysis, and signal processing regarding tensors. Applications will be given to the matrix multiplication tensor, where computer scientists have made the astounding conjecture that as n goes to infinity, it becomes essentially just as easy to matrix multiply two n by n matrices together as it is to add them.
