Query: Generalized solution of a mixed problem for linear hyperbolic system   In the first part of this article, we will prove an existence-uniqueness
result for generalized solutions of a mixed problem for linear hyperbolic
system in the Colombeau algebra. In the second part, we apply this result to a
wave propagation problem in a discontinuous environment.
