摘 要:Suppose that the two eigenvalues of system (0.1) are λ1(u, v), λ2(u, v), the corres-ponding Riemann invariants are w=w(u, v), z=z(u, v), and w=w(u, v), z=z(u, v) give a bijective smooth mapping from (u, v) plane onto (w, z) plane. Throughout this note, we always suppose that A1 u0(x), v0(x) are bounded measurable functions. A2 λ1(u, v), λ2(u, v)∈C1 and system (0.1) are strictly hyperbolic, i.e. λ1(u, v)2(u, v).
