From a July 2018 conference in Bonn, 18 papers look at dynamics from such perspectives as homotopy types and geometries below Spec(/Z/>), dynamical zeta functions of Reidemeister type and representation spaces, rigorous dimension estimates for Cantor sets arising in Zaremba theory, weak rigidity and weakly mixing enveloping semigroups, the inhomogeneous Sprinkzhuk conjecture over a local field of positive characteristics, the convergence of zeta functions for amenable groups extensions of shifts, periods of abelian differentials and dynamics, and the crossed renormalization of quadratic polynomials.
