Abstract

This paper is concerned with the existence and regularity of global attractor $A$ for a Kirchhoff wave equation with strong damping and memory in $H$ and $H^{1}$ , respectively. In order to obtain the existence of $A$ , we mainly use the energy method in the priori estimations, and then verify the asymptotic compactness of the semigroup by the method of contraction function. Finally, by decomposing the weak solutions into two parts and some elaborate calculations, we prove the regularity of $A$ .

具有强阻尼和记忆的基尔霍夫波方程全局吸引子的存在性和正则性

本文主要研究在 H 和 H1 中分别具有强阻尼和强记忆的基尔霍夫波方程的全局吸引子 A 的存在性和正则性。为了得到 A 的存在性，我们主要采用能量法进行先验估计，然后用收缩函数法验证半群的渐近紧凑性。最后，通过将弱解分解为两部分和一些精细的计算，我们证明了 A 的正则性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
