This book is a quick but precise and careful introduction to the subject of functional analysis. It covers the basic topics that can be found in a basic graduate analysis text. But it also covers more sophisticated topics such as spectral theory, convexity, and fixed-point theorems. A special feature of the book is that it contains a great many examples and even some applications. It concludes with a statement and proof of Lomonosov's dramatic result about invariant subspaces.

This Function Analysis Guide will give you a greater understanding of Function Analysis to the extent that it becomes second nature to those using the Value Methodology to improve their projects, products, and processes. Application of the techniques covered herein will result in better studies and, most importantly, better results. Lawrence D. Miles, the "Father of Value Analysis," stated "the customer wants a function." People want functions, not things. Function Analysis is considered the heart of the Value Methodology (VM), yet many people have difficulty applying its concepts and techniques to their projects, products, and processes. This document provides guidance on the process and application of function analysis, including Function Analysis System Technique (FAST) for practitioners and those who are preparing to become certified through SAVE International(R).

This book introduces functional analysis at an elementary level without assuming any background in real analysis, for example on metric spaces or Lebesgue integration. It focuses on concepts and methods relevant in applied contexts such as variational methods on Hilbert spaces, Neumann series, eigenvalue expansions for compact self-adjoint operators, weak differentiation and Sobolev spaces on intervals, and model applications to differential and integral equations. Beyond that, the final chapters on the uniform boundedness theorem, the open mapping theorem and the Hahn-Banach theorem provide a stepping-stone to more advanced texts. The exposition is clear and rigorous, featuring full and detailed proofs. Many examples illustrate the new notions and results. Each chapter concludes with a large collection of exercises, some of which are referred to in the margin of the text, tailor-made in order to guide the student digesting the new material. Optional sections and chapters supplement the mandatory parts and allow for modular teaching spanning from basic to honors track level.

This book introduces the basic principles of functional analysis and areas of Banach space theory that are close to nonlinear analysis and topology. The text can be used in graduate courses or for independent study. It includes a large number of exercises of different levels of difficulty, accompanied by hints.

Functional Analysis: A Practitioner's Guide to Implementation and Training provides practitioners with the most updated information about applying the wide span of current functional analysis (FA) methodologies geared specifically to applied service settings. The book serves as a self-instructional implementation to a broad-base of trainees and care-providers within schools, clinics, centers and human services organizations. Adopting a Behavioral Skills Training and competency-based training outcomes approach, the learning materials and activities featured in the book include suggested slideshow presentations, role-play exercises, pre- and post-training quizzes, natural setting evaluation methods, data recording forms, instructional scripts and reproducible handouts. - Covers an historical overview and the ethical considerations of functional analysis - Examines FA methodology, measurement methods and experimental designs - Teaches how to independently design, conduct and interpret FAs - Explains how to formulate FA-informed intervention plans - Presents an agile curriculum that can be customized for different providers

Functional analysis and operator theory are widely used in the description, understanding and control of dynamical systems and natural processes in physics, chemistry, medicine and the engineering sciences. Advanced Functional Analysis is a self-contained and comprehensive reference for advanced functional analysis and can serve as a guide for related research. The book can be used as a textbook in advanced functional analysis, which is a modern and important field in mathematics, for graduate and postgraduate courses and seminars at universities. At the same time, it enables the interested readers to do their own research. Features Written in a concise and fluent style Covers a broad range of topics Includes related topics from research
