On Certain Type of Sequence Spaces Defined by ð‹ − Function [PDF]
, 2019 In this paper, we introduce non-negative real valued 𜑠− function on â„ . Using 𜑠− function, we define the sequence spaces ð‘Š (ð‘“), ð‘Š 0 (ð‘“), and 𑊠∞ (ð‘“).

Some New Lacunary Strong Convergent Vector‐Valued Sequence Spaces
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 We introduce some vector‐valued sequence spaces defined by a Musielak‐Orlicz function and the concepts of lacunary convergence and strong (A)‐convergence, where A = (aik) is an infinite matrix of complex numbers. We also make an effort to study some topological properties and some inclusion relations between these spaces.

The Putnam-Fuglede property for paranormal and *-paranormal operators
Opuscula Mathematica, 2013 An operator \(T \in {\cal B}(H)\) is said to have the Putnam-Fuglede commutativity property (PF property for short) if \(T^*X = XJ\) for any \(X \in {\cal B}(K,H)\) and any isometry \(J \in {\cal B}(K)\) such that \(TX = XJ^*\). The main purpose of this paper is to examine if paranormal operators have the PF property.

Journal of Mathematics, Volume 2026, Issue 1, 2026.In this paper, we introduce new Fibonacci‐type difference sequence spaces defined by a modulus function f, specifically focusing on the sequence space lGu,v,f,p, where p = (pk) is an arbitrary bounded sequence of positive real numbers. These spaces consist of all sequences whose transforms under the generalized Fibonacci band matrix G(u, v) belong to ...

On the Paranormed Nörlund Sequence Space of Nonabsolute Type
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 Maddox defined the space ℓ(p) of the sequences x = (xk) such that ∑k=0∞ |xk|pk<∞, in Maddox, 1967. In the present paper, the Nörlund sequence space Nt(p) of nonabsolute type is introduced and proved that the spaces Nt(p) and ℓ(p) are linearly isomorphic.

Free will and paranormal beliefs [PDF]
Frontiers in Psychology, 2014 Free will is one of the fundamental aspects of human cognition. In the context of cognitive neuroscience, various experiments on time perception, sensorimotor coordination, and agency suggest the possibility that it is a robust illusion (a feeling independent of actual causal relationship with actions) constructed by neural mechanisms. Humans are known

On Some New Sequence Spaces and Their Duals
Journal of Mathematics, Volume 2024, Issue 1, 2024.In this study, we defined some new sequence spaces using regular Tribonacci matrix. We examined some properties of these spaces such as completeness, Schauder basis. We have identified α − , β−, and γ−duals of the newly created spaces.

A Class of Sequences Defined by Weak Ideal Convergence and Musielak‐Orlicz Function
Abstract and Applied Analysis, Volume 2014, Issue 1, 2014., 2014 We introduced the weak ideal convergence of new sequence spaces combining an infinite matrix of complex numbers and Musielak‐Orlicz function over normed spaces. We also study some topological properties and inclusion relation between these spaces.

Abstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013 We introduced the ideal convergence of generalized difference sequence spaces combining an infinite matrix of complex numbers with respect to λ‐sequences and the Musielak‐Orlicz function over n‐normed spaces. We also studied some topological properties and inclusion relations between these spaces.

On a New I‐Convergent Double‐Sequence Space
International Journal of Analysis, Volume 2013, Issue 1, 2013., 2013 The sequence space BVσ was introduced and studied by Mursaleen (1983). In this article we introduce the sequence space 2BVσI and study some of its properties and inclusion relations.
