Applications of Functional Analysis and Operator TheoryFunctional analysis is a powerful tool when applied to mathematical problems arising from physical situations. The present book provides, by careful selection of material, a collection of concepts and techniques essential for the modern practitioner. Emphasis is placed on the solution of equations (including nonlinear and partial differential equations). The assumed background is limited to elementary real variable theory and finite-dimensional vector spaces.

Page 4 - ... S is said to be linearly independent. An arbitrary set S of vectors in V is linearly independent iff every finite non-empty subset of S is linearly independent; otherwise it is linearly dependent. If there is a positive integer n such that V contains n but not n + 1 linearly independent vectors, V is said to be finite dimensional with dimension n. V is infinite dimensional iff it is not finite dimensional. The finite set S of vectors in V is called a basis of V iff S is linearly independent and...
