Determining the complexity of matrix multiplication is a fundamental problem of theoretical computer science. It is popularly conjectured that ω, the matrix multiplication exponent, equals 2. If true, this conjecture would yield fast algorithms for a wide array of problems in linear algebra and beyond. If instead ω > 2, can we leverage the hardness of matrix multiplication to design algorithms for other problems? In this talk, I will describe how lower bounds on ω can be used to make progress on derandomizing polynomial identity testing.
