Abstract
Given a finite group acting on a surface , the centralizer of G in the mapping class group has a natural representation given by its action on the homology . We consider the question of whether this representation has arithmetic image. Several authors have given positive and negative answers to this question. We give a complete answer when S has genus at most 3.
