Overview

Functional analysis has become one of the essential foundations of modern applied mathematics in the last decades, from the theory and numerical solution of differential equations, from optimization and probability theory to medical imaging and mathematical image processing. This textbook offers a compact introduction to the theory and is designed to be used during one semester, fitting exactly 26 lectures of 90 minutes each. It ranges from the topological fundamentals recalled from basic lectures on real analysis to spectral theory in Hilbert spaces. Special attention is given to the central results on dual spaces and weak convergence.

Reviews

I do like the book! Most impressive to me is perhaps that the whole text is just 160 pages and still the explanations do not feel condensed while really the essential points are taken care of. (Olav Nygaard, zbMATH 1461.46001, 2021)
