Delta shock wave formation in the case of triangular hyperbolic system of conservation laws. (English) Zbl 1192.35120
Summary: We describe $\delta$-shock wave generation from continuous initial data in the case of triangular conservation law system arising from “generalized pressureless gas dynamics model”. We use smooth approximations in the weak sense that are more general than small viscosity approximations.
