SUMMARY:The complexity of matrix multiplication approached via algebraic geometry and representation theory
DESCRIPTION:Speaker: JM Landsberg\, Texas A&M \nTitle: The complexity of matrix multiplication approached via algebraic geometry and representation theory \nAbstract: In 1968 V. Strassen discovered the way we usually multiply matrices is not the most efficient possible\, and after considerable work by many authors\, it is generally conjectured by computer scientists that as the size of matrices becomes large\, it becomes almost as easy to multiply them as it is to add them. I will give a brief history of the problem\, explain how this conjecture is naturally understood in the framework of classical algebraic geometry and representation theory\, and conclude by describing recent advances using more sophisticated tools from algebraic geometry. For most of the talk\, no knowledge of algebraic geometry or representation theory will be needed.
