Pseudo almost periodic functions in Banach spaces. (English) Zbl 1234.43002
New York, NY: Nova Science Publishers (ISBN 978-1-60021-637-4). xiv, 132 p. (2007).
Publisher’s description: This book provides the reader with a comprehensive and accessible introduction to the concepts of almost periodicity and pseudo almost periodicity as well as their applications to differential equations, partial differential equations, integral equations, and partial neutral functional differential equations with delay on Banach spaces. Further, the book offers various suffcient conditions, which do guarantee the existence and uniqueness of (pseudo) almost periodic solutions to the heat equation, reaction-diffusion equation, transport equation, logistic equation with delay, and neutral partial functional differential equations with delays arising in control systems. To obtain those existence results, the author makes use of various techniques such as semigroup methods combined with some classical fixed-point theorems, the so-called method of the invariant subspaces for unbounded linear operators, Zima’s fixed-point theorem, and many more.
