摘要
研究一类解耦非线性双曲守恒律系统的广义黎曼问题.在适当的初值条件下,构造了该问题的狄拉克激波(δ-激波)解,并证明了包含δ-激波的整体间断解的存在唯一性.
The generalized Riemann problem for a class of deeoupled nonlinear hyperbolic system of conservation laws is studied. Under a suitable condition of initial data, the Delta-shock solution is constructed, and the existence and uniqueness of global discontinuous solutions containing one delta shock wave is proved.
