These are excellent and rigorous lecture notes in Functional Analysis, which are offered in two variants: F.A. 1 (85p.): lecture notes based on Banach spaces and operators, topological spaces are included. F.A. 2 (127p.): lecture notes based on topological vector spaces as a main theme, Banach spaces and Frechet (metric) spaces are included. These two variants (when combined) provide a lot of fundamental and important material, sufficient for a serious undergraduate (or graduate) course in Functional Analysis (which doesn’t include measure theory and integration). All theorems are stated with proofs ! Author’s approach to all themes is “gentle” but rigorous, these notes (like other from the same athor) are highly recommended to all who wish to learn fundamentals of Functional Analysis from excellent source !
