Abstract: | In this paper, we consider a singularly perturbed problem of a kind of quasilinear hyperbolic-parabolic equations, subject
to initial-boundary value conditions with moving boundary:
When certain assumptions are satisfied and ε is sufficiently small, the solution of this problem has a generalized asymptotic
expansion (in the Van der Corput sense), which takes the sufficiently smooth solution of the reduced problem as the first
term, and is uniformly valid in domain Q where the sufficiently smooth solution exists. The layer exists in the neighborhood
of t=0. This paper is the development of references 3–5].
