Abstract: Let q>1 be an integer, and let P is a times q invariant ergodic measure with positive entropy. We shall discuss the proof of the following result: Let m>1 be an integer independent of q. Then for P typical x the orbit of (x,x) under the diagonal toral endomorphism (times q, times m) equidistributes for the product measure of P with the Lebesgue measure. Specially, we shall discuss in detail a Theorem that provides sufficient conditions for a measure that is (times q, times m) invariant to be equal to the product of its marginals.
