New border rank lower bounds for matrix multiplication
Abstract: Progress on both upper and lower bounds for matrix multiplication have been stalled in the past few years. I will explain why it was stalled and how Buczynska-Buczynski's theory of border apolarity has opened doors to progress on lower and perhaps even upper bounds. If time permits, I will also explain new hurdles that will need to be surmounted. This is joint work with A. Conner and A. Harper.
