Main Title: Potter, Wielandt, and Drazin on the matrix equation $AB = \omega BA$, with some new answers to old questions

Type: Research Paper
Abstract: In this partly historical and partly research oriented note, we display a page of an unpublished mathematical diary of Helmut Wielandt's for 1951. There he gives a new proof of a theorem due to H.~S.~A.~Potter on the matrix equation $AB = \omega BA$, which is related to the $q$-binomial theorem, and asks some further questions, which we answer. We also describe results by M.~P.~Drazin and others on this equation.
