Matrix multiplication via matrix groups

Jonah Blasiak, Henry Cohn, Joshua A. Grochow +2

In 2003, Cohn and Umans proposed a group-theoretic approach to bounding the exponent of matrix multiplication. Previous work within this approach ruled out certain families of grou…

Which groups are amenable to proving exponent two for matrix multiplication?

Jonah Blasiak, Thomas Church, Henry Cohn +2

The Cohn-Umans group-theoretic approach to matrix multiplication suggests embedding matrix multiplication into group algebra multiplication, and bounding ω in terms of the repres…
