Coorbit Space Theory for Quasi-Banach Spaces
We generalize the classical coorbit space theory developed by Feichtinger and Gröchenig to quasi-Banach spaces. As a main result we provide atomic decompositions for coorbit spaces defined with respect to quasi-Banach spaces. These atomic decompositions are used to prove fast convergence rates of best n-term approximation schemes. We apply the abstract theory to time-frequency analysis of modul...
متن کاملNon-smooth Analysis, Optimisation Theory and Banach Space Theory
The questions listed here do not necessarily represent the most significant problems from the areas of Non-smooth Analysis, Optimisation theory and Banach space theory, but rather, they represent a selection of problems that are of interest to the authors. 1. Weak Asplund spaces Let X be a Banach space. We say that a function φ : X → R is Gâteaux differentiable at x ∈ X if there exists a contin...
متن کاملNigel Kalton’s Work in Isometrical Banach Space Theory
Nigel Kalton was one of the greatest mathematicians of the last 40 years, although he did his best to conceal this fact. An outsider wouldn’t recognise the mathematical giant that he was in this modest person who was always friendly and good-humoured and who was more than willing to share his ideas with everyone. Nigel published more than 260 papers (including several books) not only in Banach ...
متن کاملSeparable Banach Space Theory Needs Strong Set Existence Axioms
We investigate the strength of set existence axioms needed for separable Banach space theory. We show that a very strong axiom, Π1 comprehension, is needed to prove such basic facts as the existence of the weak-∗ closure of any norm-closed subspace of `1 = c0. This is in contrast to earlier work [6, 4, 7, 23, 22] in which theorems of separable Banach space theory were proved in very weak subsys...
متن کاملWeak * Sequential Closures in Banach Space Theory and Their Applications
Let X be a (real or complex) Banach space, its dual Banach space will be denoted by X *. We use standard notation and terminology of Banach space theory, see J.Lindenstrauss and L.Tzafriri [LT]. By a subspace we mean a linear, but not necessarily closed, subspace. We also assume some knowledge of general topology and ordinal numbers, see P.S.Aleksandrov[A]. Definition 1.1. Let A be a subset of ...
