We'll take an introductory peek into the measure rigidity program for higher-rank abelian actions by looking at the simplest case, Anosov Z^k actions on (k+1)-dimensional tori. The main structures and ideas appearing in the theory will be explained, as well as how the situation becomes more complicated under fewer assumptions.
