Abstract

This research project is a study of complex structures on real Banach spaces, to be developed during the candidate's doctoral studies at the Institute of Mathematics and Statistics (IME-USP). The candidate will study the spaces successively built by Bourgain, Kalton and Ferenczi, which are examples of Banach spaces with at least two distinct complex structures. The first goal will be to determine the exact number of different complex structures which have each of the first two examples. From the different methods developed for studying these three spaces and the study of Fredholm theory, the candidate will try to define a space with just a countable infinite number of complex structures. In addition, the student will use the descriptive set theory applied to Banach space theory, to study the number of complex structures in a given space, in the framework of equivalence relations on Polish spaces.
