AI总结:

本文针对源于大尺度结构形成、可作为二阶排队模型的一维零压动力学系统,构建了四分之一平面上带两类Riemann解初边值问题的弱渐近解并分析了波相互作用。

摘要:

本文研究一类在众多物理现象建模中出现的方程组。该系统最初用于描述大尺度结构形成,近期被推导为一种二阶排队模型。我们构建了该系统初边值问题的弱渐近解,并研究了四分之一平面$\boldsymbol{\{(x,t): x>0,t>0\boldsymbol{\}}}$内波的相互作用,其中边界条件为中心在$(0,0)$的Riemann解,初始条件包含中心在$(x_0,0)$($x_0>0$)的Riemann解。

英文摘要:

In 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 $\{(x,t): x>0,t>0\}$ with boundary Riemann solution centered at $(0,0)$ and Riemann solution centered at a point $(x_0,0), x_0>0$.
