The goal of this textbook is to provide an introduction to the methods and language of functional analysis, including Hilbert spaces, Fredholm theory for compact operators, and spectral theory of self-adjoint operators. It also presents the basic theorems and methods of abstract functional analysis and a few applications of these methods to Banach algebras and the theory of unbounded self-adjoint operators. The text corresponds to material for two semester courses (Part I and Part II, respectively), and it is as self-contained as possible. The only prerequisites for the first part are minimal amounts of linear algebra and calculus. However, for the second course (Part II), it is useful to have some knowledge of topology and measure theory. Each chapter is followed by numerous exercises, whose solutions are given at the end of the book.
The book features new directions in analysis, with an emphasis on Hilbert space, mathematical physics, and stochastic processes.

But now, again by the WH-frame Identity, we have for all bounded, compactly supported f e L*(R), ||f||* = F(f) + F)(f) = ||f||* + F)(f). That is, F2(f) = 0, for all bounded compactly supported f e L*(R). Now fix ko - 1 and let I be any ...
All winged animals can fly. All senators are currently over 36 years old. An ostrich has wings. Everett is not over 36. ∴ An ostrich can fly. ∴ Everett is not a senator. Solution. These examples illustrate the irrelevance of the truth ...
