【Abstract】 This paper deals with the well-posedness problem for a class of weakly semilinear telegraph equations with intial value in an infinite region {(x,t)|x∈ R,0<t<L|ε|}.The asymptotic validity of formal approximations for the solutions in the region is established.An application for the asymptotic theory obtained is given.更多还原
