Linearization of the Riemann problem for a triangular system of conservation laws and delta shock wave formation process

Mathematical Methods in Applied Sciences. 2010. Vol. 33. P. 904-921.
Danilov V., Mitrovic D., Bojkovic V.

Using the weak asymptotic method, we approximate a triangular system of conservation laws arising from the so-called generalized pressureless gas dynamics by a diagonal linear system. Then, we apply the usual method of characteristics to find approximate solution to the original system. As a consequence, we shall see how the delta shock wave naturally arises along the characteristics. Also, we propose a procedure that could be applied to more general systems of conservation laws.
