"Foundations of Functional Analysis" provides fundamental concepts about the theory, application and various methods involving functional analysis for students, teachers, scientists and engineers. Divided into three parts it covers: basic facts of linear algebra and real analysis; normed spaces, contraction mappings, linear operators between normed spaces and fundamental results on these topics; and hilbert spaces and the representation of continuous linear function with applications. In this self-contained book, all the concepts, results and their consequences are motivated and illustrated by numerous examples in each chapter with carefully chosen exercises.
