This paper characterizes those pseudo-Anosov mappings whose entropy can be detected homologically by taking a limit over finite covers. The proof is via complex-analytic methods. The same methods show the natural map Mg → Ah, which sends a Riemann surface to the Jacobians of all of its finite covers, is a contraction in most directions.
