On almost commuting matrices T. V. Shulman
https://youtu.be/pE4bgFd9OSs Abstract: Questions of whether almost commuting matrices are necessarily close to commuting ones are old. They are reformulated using $C^*$-algebra theory and have somewhat topological nature. We investigate which relations for families of commuting matrices are stable under small perturbations and give some applications. Joint work with Dominic Enders.
