On Schauder Frames in Conjugate Banach Spaces [PDF]
, 2013 Weak*-Schauder frame in conjugate Banach spaces has been introduced and studied. A sufficient condition for the existence of weak*-Schauder frame in the conjugate space of a separable Banach space has been given.

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.This work investigates the existence of infinitely many nontrivial weak solutions to a boundary value problem involving the right‐sided and left‐sided ψ‐Hilfer fractional derivative and ψ‐Riemann–Liouville fractional integral operators. Using variational methods and critical point theory, we obtain new existence criteria for solutions of the given ...

New Fixed‐Point and Common Fixed‐Point Results in Finite‐Dimensional Normed Pre‐A∗ Vector Spaces
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.This paper establishes new fixed‐point and common fixed‐point theorems for continuous and asymptotically regular self‐maps defined on finite‐dimensional normed pre‐A∗ vector spaces over σ‐complete pre‐A∗‐algebras. We prove that every continuous and asymptotically regular self‐map on such a space has at least one fixed point (Theorem 2).

Almost convergent sequence spaces derived by the domain of quadruple band matrix
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2020 In this work, we construct the sequence spaces f(Q(r,s,t,u)), f0(Q(r,s,t,u)) and fs(Q(r,s,t,u)), where Q(r,s,t,u) is quadruple band matrix which generalizes the matrices Δ3, B(r,s,t), Δ2, B(r,s) and Δ, where Δ3, B(r,s,t), Δ2, B(r,s) and Δ are called ...

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.Fractional differential equations (FDEs) are of great significance for describing complex physical processes with memory and genetic characteristics. The introduction of the p‐Laplacian operator can expand its applicability in nonlinear problems. To explore the uniqueness multiplicity, and variety of solutions to p‐Laplacian differential equations with

Some normed binomial difference sequence spaces related to the ℓ p $\ell_{p}$ spaces
Journal of Inequalities and Applications, 2017 The aim of this paper is to introduce the normed binomial sequence spaces b p r , s ( ∇ ) $b^{r,s}_{p}(\nabla)$ by combining the binomial transformation and difference operator, where 1 ≤ p ≤ ∞ $1\leq p\leq\infty$ .
