Kaleva-Seikkala’s Type Fuzzy b-Metric Spaces and Several Contraction Mappings
Journal of Function Spaces, 2022 In this paper, we introduce the concept of Kaleva-Seikkala’s type fuzzy b-metric spaces as a generalization of the notion of b-metric spaces and fuzzy metric spaces.

New Sequence Spaces and Function Spaces on Interval [0,1]
Journal of Function Spaces and Applications, 2013 We study the sequence spaces and the spaces of functions defined on interval 0,1 in this paper. By a new summation method of sequences, we find out some new sequence spaces that are interpolating into spaces between ℓp and ℓq and function spaces that are

A double projection algorithm for quasimonotone variational inequalities in Banach spaces
Journal of Inequalities and Applications, 2018 We propose a double projection algorithm for solving variational inequality problems in Banach spaces. We establish the strong convergence of the whole sequence generated by the proposed method under the quasimonotone and uniform continuity on bounded ...

Mathematics, 2020 Kannan maps have inspired a branch of metric fixed point theory devoted to the extension of the classical Banach contraction principle. The study of these maps in modular vector spaces was attempted timidly and was not successful.

Entire Analytic Functions of Unbounded Type on Banach Spaces and Their Lineability
Axioms, 2021 In the paper we establish some conditions under which a given sequence of polynomials on a Banach space X supports entire functions of unbounded type, and construct some counter examples.

Remarks on Asymptotic Centers and Fixed Points
Abstract and Applied Analysis, 2010 We introduce a class of nonlinear continuous mappings defined on a bounded closed convex subset of a Banach space X. We characterize the Banach spaces in which every asymptotic center of each bounded sequence in any weakly compact convex subset is ...

Hypercyclic operators on topological vector spaces
, 2010 Bonet, Frerick, Peris and Wengenroth constructed a hypercyclic operator on the locally convex direct sum of countably many copies of the Banach space $\ell_1$. We extend this result.

AN OPERATOR SUMMABILITY OF SEQUENCES IN BANACH SPACES [PDF]
Glasgow Mathematical Journal, 2013 AbstractLet 1 ≤ p < ∞. A sequence 〈 xn 〉 in a Banach space X is defined to be p-operator summable if for each 〈 fn 〉 ∈ lw*p(X*) we have 〈〈 fn(xk)〉k〉n ∈ lsp(lp). Every norm p-summable sequence in a Banach space is operator p-summable whereas in its turn every operator p-summable sequence is weakly p-summable.
