摘要:

This paper is concerned with the initial boundary value problem for a vis-
coelastic model with relaxation. Under the only assumption that the C0-norm of the
initial data is small, without smallness hypothesis for the C1-norm, the existence of the
global smooth solution to the corresponding initial boundary value problem is proved.
The analysis is based on some a priori estimates obtained by the “maximum principle” of
first-order quasilinear hyperbolic system.
