On a class of nonlinear hyperbolic systems
The author deals with an initial-boundary value problem associated with a nonlinear telegraph PDE system. All the results reported in this paper are slight extensions of some theorems in the reviewer's book [Nonlinear evolution equations and applications, Reidel (1988; Zbl 0696.35078)]. The only difference here is the presence of some extra functions (depending on \(t\)) in the boundary conditions, but no essential changes are needed in the treatment.
