Semadeni Derivative of Banach Spaces and Functions on Nonmetrizable Rectangles

A 19-minute lecture by Maciej Korpalski exploring the Semadeni derivative of Banach spaces and functions on nonmetrizable rectangles. Delivered as part of the Workshop on "Structures in Banach Spaces" held at the Erwin Schrödinger International Institute for Mathematics and Physics (ESI) from March 17-21, 2025. Delve into advanced mathematical concepts at the intersection of functional analysis and topology, examining how Semadeni derivatives apply to non-standard geometric structures. For detailed information about the mathematical framework and specific theorems discussed, refer to the abstract available on the ESI website.
