Title:  Mapping class groups, homology & finite covers of surfaces

Abstract:   Let S be a orientable surface of negative Euler characteristic. Ã� We will discuss the action of pseudo-Anosov mapping classes of S on the homology of various finite covers of S to which they lift. Ã� We will be particularly interested in finding a lift of each pseudo-Anosov mapping class for which the homological spectral radius is greater than one. Ã� For a given mapping class, we will relate the study of this problem to the topology of the mapping torus.
