Equicontinuity and Almost Periodic Functions1
Let A be a separated uniform space, C(X, X) the set of continuous functions of X into X, and C(X) the set of real valued continuous functions on X provided with the topology of uniform convergence. For fEC(X) and aEC(X, X), fa will denote that element of C(X) such that (fa)(x) =f(xa)(xEX). Let fEC(X) and A EC(X, X). Then f is said to be almost periodic with respect to A if fA = [fa\ aEA ] is a ...
متن کاملOn Principle of Equicontinuity
The main purpose of this paper is to prove some results of uniform boundedness principle type without the use of Baire’s category theorem in certain topological vector spaces; this provides an alternate route and important technique to establish certain basic results of functional analysis. As applications, among other results, versions of the Banach-Steinhaus theorem and the Nikodym boundednes...
متن کاملWeak Amenability and 2-weak Amenability of Beurling Algebras
Let Lω(G) be a Beurling algebra on a locally compact abelian group G. We look for general conditions on the weight which allows the vanishing of continuous derivations of Lω(G). This leads us to introducing vector-valued Beurling algebras and considering the translation of operators on them. This is then used to connect the augmentation ideal to the behavior of derivation space. We apply these ...
متن کاملAmenability and co-amenability in non-abelian group duality
Leptin’s theorem asserts that a locally compact group is amenable if and only if its Fourier algebra has a bounded (by one) approximate identity. In the language of locally compact quantum groups—in the sense of J. Kustermans and S. Vaes—, it states that a locally compact group is amenable if and only if its quantum group dual is co-amenable. It is an open problem whether this is true for gener...
متن کاملPointwise Boundedness and Equicontinuity in Β-duals
Let E be a vector valued sequence space with operator valued βdual E . If E satisfies certain gliding hump assumptions, we show that pointwise bounded subsets of E are sequentially equicontinuous. The result is established by considering uniform convergence of the elements in E .
