Let A and B be two-by-two volume preserving matrices with integer coefficients spanning a non-solvable group.
Let x be an irrational point on the 2-torus.
We toss A or B, apply it to x, get another irrational point y, do it again to y, get a point z, and again...
We prove that this random trajectory is almost surely equidistributed.
This is a joint work with JFQuint.
