WebTheorem: If A and B are n×n matrices, then char(AB) = char(BA). A beautiful proof of this was given in: J. Schmid, A remark on characteristic polyno-mials, Am. Math. Monthly, 77 (1970), 998-999. In fact, he proved a stronger result, that be-comes the theorem above if we have m = n: Theorem: Let A be an n × m matrix and B an m × n matrix.
