Abstract

In this paper, we consider an initial value problem for the 2-D compressible Navier-Stokes equations without heat conductivity. We prove the global existence of a strong solution when the initial perturbation is small in

H^{2}

and its

L^{1}

norm is bounded. Moreover, we derive some decay estimate for such a solution.

二维无导热可压缩Navier-Stokes方程的整体存在性和大时间行为

本文研究无导热的二维可压缩Navier-Stokes方程的初值问题。我们证明了当初始扰动在h2及其L中很小时，一个强解的整体存在性一个范数是有界的。此外，我们还推导了这种解的一些衰减估计。

期刊介绍： Abstract and Applied Analysis is a mathematical journal devoted exclusively to the publication of high-quality research papers in the fields of abstract and applied analysis. Emphasis is placed on important developments in classical analysis, linear and nonlinear functional analysis, ordinary and partial differential equations, optimization theory, and control theory. Abstract and Applied Analysis supports the publication of original material involving the complete solution of significant problems in the above disciplines. Abstract and Applied Analysis also encourages the publication of timely and thorough survey articles on current trends in the theory and applications of analysis.
