Rigidity of real-analytic actions of SL(n,Z)SL(n,\Z) on \T^n: A case of realization of Zimmer program

We prove that any real-analytic action of $SL(n,\Z), n\ge 3$ with standard homotopy data that preserves an ergodic measure $\mu$ whose support is not contained in a ball, is analytically conjugate on an open invariant set to the standard linear action on the complement to a finite union of periodic orbits
