 Banach SpacesUniversity of OxfordPDF  62 Pages  EnglishThis note will provide a firm knowledge
of real and complex normed vector spaces, with geometric and topological
properties. Reader will be familiar with the notions of completeness,
separability and density, will know the properties of a Banach space and
important examples, and will be able to prove results relating to the Hahn–Banach
Theorem. They will have developed an understanding of the theory of bounded
linear operators on a Banach space.
