Query: Decay for the wave and Schroedinger evolutions on manifolds with conical
  ends, Part I   Global in time dispersive estimates for the Schroedinger and wave evolutions
are obtained on manifolds with conical ends whose Hamiltonian flow exhibits
trapping. This paper deals with the case of initial data with "zero angular
momentum".
