Query: Symmetry Decomposition of Chaotic Dynamics   Discrete symmetries of dynamical flows give rise to relations between
periodic orbits, reduce the dynamics to a fundamental domain, and lead to
factorizations of zeta functions. These factorizations in turn reduce the labor
and improve the convergence of cycle expansions for classical and quantum
spectra associated with the flow. In this paper the general formalism is
developed, with the $N$-disk pinball model used as a concrete example and a
series of physically interesting cases worked out in detail.
