Abstract

In this paper we prove the existence of weak solutions for a class of quasilinear parabolic systems, which correspond to diffusion problems, in the form where Ω is a bounded open domain of be given and The function v belongs to is in a moving and dissolving substance, the dissolution is described by f and the motion by g. We prove the existence result by using Galerkin’s approximation and the theory of Young measures.

具有低阶项的拟线性抛物型系统的一个存在性结果
本文证明了一类与扩散问题相对应的拟线性抛物系统弱解的存在性,其形式为Ω是给定的有界开域,函数v属于运动和溶解的物质,溶解用f描述,运动用g描述。我们利用伽辽金近似和杨测度理论证明了弱解的存在性结果。
