摘要:

This article considers Cauchy problem ut − (uv)x = 0, vt − ux = 0, (E) u(x, 0) = u0(x) > 0, v(x, 0) = v0(x). (I) A necessary and sufficient condition in guaranteeing that Cauchy problem admits a global C1-solution on t  0 is obtained.

关键词: Nonlinear hyperbolic system, Cauchy problem, global C1-solution
