Abstract

In this paper, we investigate an initial boundary value problem for a nonlinear pseudoparabolic equation. At first, by applying the Faedo-Galerkin, we prove local existence and uniqueness results. Next, by constructing Lyapunov functional, we establish a sufficient condition to obtain the global existence and exponential decay of weak solutions.

一类含粘弹性项的非线性拟抛物方程解的局部存在性和指数衰减

本文研究了一类非线性拟抛物方程的初边值问题。首先，通过应用Faedo-Galerkin，我们证明了局部存在性和唯一性的结果。其次，通过构造李雅普诺夫泛函，我们建立了弱解的全局存在性和指数衰减性的充分条件。
