Weakly unconditionally Cauchy series and Fibonacci sequence spaces
We study new sequence spaces associated to sequences in normed spaces and the band matrix F̂ defined by the Fibonacci sequence. We give some characterizations of continuous linear operators and weakly unconditionally Cauchy series by means of completeness of the new sequence spaces. Also, we characterize the barreledness of a normed space via weakly∗ unconditionally Cauchy series in [Formula: se...
متن کاملRemarks on completeness of lattice-valued Cauchy spaces
We study different completeness definitions for two categories of lattice-valued Cauchy spaces and the relations between these definitions. We also show the equivalence of a so-called completion axiom and the existence of a completion.
متن کاملCharacterizations of Series in Banach Spaces
In this paper we prove several new characterizations of weakly unconditionally Cauchy series in Banach spaces and in the dual space of a normed space. For a given series ζ, we consider the spaces S(ζ), Sw(ζ) and S0(ζ) of bounded sequences of real numbers (ai)i such that the series P i aixi is convergent, weakly convergent or ∗-weakly convergent, respectively. By means of these spaces we charact...
متن کاملCharacterizations of weak Cauchy sn - symmetric spaces
This paper proves that a space X is a weak Cauchy sn-symmetric space iff it is a sequentially-quotient, π-image of a metric space, which answers a question posed by Z. Li. 2000 Mathematics Subject Classification: 54C05, 54C10, 54E40.
