Kontsevich–Zorich cocycle

E904569

The Kontsevich–Zorich cocycle is a dynamical system arising from the action of the Teichmüller geodesic flow on the Hodge bundle over moduli spaces of Riemann surfaces, central to understanding deviations of ergodic averages and Lyapunov exponents in flat surface dynamics.
