Appendix. Topics in Linear Analysis
A Banach space is a vector space with very attractive convergence properties. For our purposes, the most important Banach spaces are spaces of functions. Formally, a Banach space is a complete, normed, vector space. Let us now define each of these terms. By a scalar we mean a real or complex number.
