Title: Notes from Operator Theory and Theory of Function spaces

Speaker: Jan Lang

Abstract: In this talk, we will explore the deep connections between Operator Theory, the Theory of Function Spaces and other areas of mathematics.

Special attention will be given to the interplay between the structural properties of these spaces—such as embeddings, duality, and interpolation—and the behavior of operators defined on them. We will also discuss recent advances in understanding the non-compactness properties of operators, particularly those arising in the context of harmonic analysis and partial differential equations.
