一类解耦双曲守恒律系统的狄拉克激波

Delta shock waves for a class of decoupled hyperbolic system of conservation laws

研究一类解耦的具有线性退化特征的非严格或严格双曲守恒律系统的黎曼问题.借助特征分析方法,在广义Rankine-Hugoniot条件和熵条件下,获得该问题的狄拉克激波解.

Riemann problems for a class of decoupled non-strictly or strictly hyperbolic system of conservation laws, which have a linearly degenerate characteristic, are studied. With the help of characteristic method, under generalized Rankine-Hugoniot relation and entropy condition, delta-shock solutions are obtained.
