This is a short course on Banach space theory with special emphasis on certain aspects of the classical theory. In particular the course focuses on three major topics: the elementary theory of Schauder bases an introduction to Lp spaces and an introduction to C(K) spaces. While these topics can be traced back to Banach himself our primary interest is in the postwar renaissance of Banach space theory brought about by James Lindenstrauss Mazur Namioka Pelczynski and others. Their elegant and insightful results are useful in many contemporary research endeavors and deserve greater publicity. By way of prerequisites the reader will need an elementary understanding of functional analysis and at least a passing familiarity with abstract measure theory. An introductory course in topology would also be helpful; however the text includes a brief appendix on the topology needed for the course. Language: English
