Propagation of Branching Conormal Asymptotics for Hyperbolic Cauchy Problems, monograph of Courant, Hilbert contains classical statements for second order equations: If the Cauchy data have a jump the solution of the Cauchy problem also jumps in the normal direction to the characteristic manifold. Many boundary value problems lead to solutions with asymptotics (cf. e.g.
