Asymptotic of solutions of cauchy - dirichlet problem for hyperbolic equation in infinit cylinders with non - smooth base

The paper "Asymptotic of solutions of cauchy - dirichlet problem for hyperbolic equation in infinit cylinders with non - smooth base" is concerned with the asymptotical expansions of generalized solutions of the Cauchy-Dirichlet problem for second order hyperbolic equation in domains with a conical points.
