Elementary Functional Analysis
Introductory text covers basic structures of mathematical analysis (linear spaces, metric spaces, normed linear spaces, etc.), differential equations, orthogonal expansions, Fourier transforms — including problems in the complex domain, especially involving the Laplace transform — and more. Each chapter includes a set of problems, with hints and answers. Bibliography. 1974 edition.
