Abstract
Consider a pair of genuinely nonlinear strictly hyperbolic conservation lawsU t +F(U) x =0 with initial dataU(O,X)=U o (X). Suppose that the initial dataU o (X)=U 1 (X)+U 2 (X), whereU 1 (X) will issue rarefaction waves only,U 2 (X) has any finite total variation and sufficiently small deviation. We prove that the Cauchy problem has a global solution.
