The study of interpolation theory motivates the concept of analytic family. These families try to capture the notion of an analytic function which values are Banach spaces, and they arise naturally when we study the complex interpolation methods for pairs and families of Banach spaces. We are interested in what corresponds to the process of differentiation of those families, which generates the so-called derived spaces. This process is closely linked to the homological theory of Banach spaces, as the derived spaces are twisted sums of the spaces that compose the family. Ideally, properties of the analytic family should induce properties of the derived spaces. Likewise, properties of the derived spaces should imply corresponding properties for the analytic families. Thus, this project proposes the study of how properties of derived spaces generated by analytic families of Banach spaces are related to properties of those families. (AU)
