The book provides an introduction to the topic followed by some important topics like linear spaces, metric space, Banach spaces, Hilbert spaces, Banach algebra and finite dimensional spectral theory, Emphasis is on giving a number of examples to to illustrate abstract concepts of functional analysis. Exercises of various levels of difficulties are given at the end of every chapter. A few solved examples are also worked out. The reader friendly systematic presentation gives to the readers an idea about the model questions and helps them to the focused. This book is intended as a textbook of course on Functional Analysis but it also intends to be useful for scientist and engineers.
