Weak Solution to Pressureless Type System

Feimin Huang

Abstract: In this paper, we study the Cauchy problem for a pressureless type system. The Riemann solutions only include two elementary waves: delta-wave and contac discontinuity. The existence of entropy solution is established by studying the interaction of the elementary waves and the generalized characeristics introduced in Dafermos [7].
