Abstract

The aim of this post-doctoral project is to develop research related to the area of twisted sums of Banach spaces, and more specifically in relation to operator ideals and perturbations by small norm operators. The supervisor will be Valentin Ferenczi (PR). The candidate is expected to interact with other members of the group specializing in twisted sums, such as W. Corrêa (PA), W. Cuellar (PA), and students linked to the project. Relations with operators in Banach spaces of analytic functions, as well as holomorphic dynamics, will be investigated. (AU)
