Weak asymptotic solution of one dimensional zero pressure dynamics system in the quarter plane

Abstract

AbstractIn this paper we study a system of equations which appear in the modelling of many physical phenomena. Initially this system appeared in description of the large scale structure formation. Recently it is derived as a second order queueing model. We construct weakly asymptotic solutions of the initial boundary value problem for the system and interaction of waves in the quarter plane with boundary Riemann solution centered at (0,0) and Riemann solution centered at a point .
