Expansion of Bessel and g-Bessel sequences to dual frames and dual g-frames
In this paper we study the duality of Bessel and g-Bessel sequences in Hilbert spaces. We show that a Bessel sequence is an inner summand of a frame and the sum of any Bessel sequence with Bessel bound less than one with a Parseval frame is a frame. Next we develop this results to the g-frame situation.

متن کاملFlows: Cocyclic and Almost Cocyclic
A flow on a compact Hausdorff space is an automorphism. Using the closed structure on the category of uniform spaces, a flow gives rise, by iteration, to an action of the integers on the topological group of automorphisms of the object. We study special classes of flows: periodic, cocyclic, and almost cocyclic, mainly in term of the possibility of extending this action continuously to various c...
متن کاملRecognizability for Sequences of Morphisms
We investigate different notions of recognizability for a free monoid morphism σ : A∗ → B∗. Full recognizability occurs when each (aperiodic) point in BZ admits at most one tiling with words σ(a), a ∈ A. This is stronger than the classical notion of recognizability of a substitution σ : A∗ → A∗, where the tiling must be compatible with the language of the substitution. We show that if |A| = 2, ...
متن کاملTransforming Sequences using Threaded Morphisms
Sequences are very useful structures in programming languages. Functional programming languages allow the convenient deenition of transformations between sequence algebras and other types of data algebra. Sequence homomorphisms are an important class of such transformations. However, not all desired transformations can be expressed as homomor-phisms. This paper describes a class of transformati...
