LetGbe a semisimple Lie group acting on a spaceX, letμbe a symmetric compactly supported measure onG, and letAbe a strongly irreducible linear cocycle over the action ofG. We then have a random walk onX, and letTbe the associated shift map. We show that, under certain assumptions, the cocycleAover the action ofTis conjugate to a block conformal cocycle.This statement is used in the recent paper by Eskin–Mirzakhani on the classification of invariant measures for the SL(2, ℝ) action on moduli space. The ingredients of the proof are essentially contained in the papers of Guivarch and Raugi and also Goldsheid and Margulis.
