Download or read book Elements of Geometry of Balls in Banach Spaces written by Kazimierz Goebel and published by Oxford University Press. This book was released on 2018-09-06 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the subjects of functional analysis is classification of Banach spaces depending on various properties of the unit ball. The need of such considerations comes from a number of applications to problems of mathematical analysis. The list of subjects includes: differential calculus in normed spaces, approximation theory, weak topologies and reflexivity, general theory of convexity and convex functions, metric fixed point theory and others. The book presents basic facts from this field.
