摘要

本文研究了Hilbert空间中具有无限记忆和时滞的抽象热弹性系统。在一些合适的条件下，利用半群理论证明了该方法的适定性。由于阻尼可以使系统稳定，而时滞可以使系统失稳，因此讨论了阻尼与时滞项的相互作用，得到了当阻尼的作用大于时滞的作用时系统是均匀稳定的。通过建立与系统能量等效的合适的Lyapunov泛函，我们还建立了抽象热弹性系统的一般能量衰减结果。

General stability of abstract thermoelastic system with infinite memory and delay

In this paper we study an abstract thermoelastic system in Hilbert space with infinite memory and time delay. Under some suitable conditions, we prove the well-posedness by invoking semigroup theory. Since the damping may stabilize the system while the delay may destabilize it, we discuss the interaction between the damping and the delay term, and obtain that the system is uniformly stable when the effect of damping is greater than that of time delay. By establishing suitable Lyapunov functionals which are equivalent to the energy of system we also establish the general energy decay results for abstract thermoelastic system.

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.
