摘要：

In this paper we consider a system of semilinear wave equations in two space dimensions and with propagation speeds possibly different from one. Under smallness assumptions on the data, we show lower bounds foe the life span of classical solutions. (C) 2003 Elsevier Science (USA). All rights reserved.
