Kannan Nonexpansive Mappings on Nakano Sequence Space of Soft Reals with Some Applications
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We developed the operators ideal in this article by extending s‐soft reals and a particular space of sequences with soft real numbers. The criteria necessary for the Nakano sequence space of soft real numbers given with the definite function to be prequasi Banach and closed are investigated.

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We have defined and studied the weighted Nakano sequence spaces of fuzzy functions. We have constructed the ideal generated by extended s‐fuzzy functions and the sequence spaces of fuzzy functions. We present some topological and geometric structures of this class of ideal and multiplication mappings acting on this sequence space of fuzzy functions ...

Generalized Multiquartic Mappings, Stability, and Nonstability
Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 In this article, a generalized form of n‐quartic mappings is introduced. The structure of such mappings is studied, and in fact, it is shown that every multiquartic mapping can be described as an equation, namely, the (generalized) multiquartic functional equation.

Characterization and Stability of Multi‐Euler‐Lagrange Quadratic Functional Equations
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 The aim of the current article is to characterize and to prove the stability of multi‐Euler‐Lagrange quadratic mappings. In other words, it reduces a system of equations defining the multi‐Euler‐Lagrange quadratic mappings to an equation, say, the multi‐Euler‐Lagrange quadratic functional equation.

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We have defined the variable exponent of the Cesàro complex function space of formal power series. We have constructed the prequasi‐ideal generated by s -numbers and this new space of complex functions. We present some topological and geometric structures of this class of ideal. The existence of Caristi’s fixed point is examined.

GENERALISING QUASINORMAL SUBGROUPS [PDF]
Bulletin of the Australian Mathematical Society, 2012 AbstractIn Cossey and Stonehewer [‘On the rarity of quasinormal subgroups’, Rend. Semin. Mat. Univ. Padova125 (2011), 81–105] it is shown that for any odd prime p and integer n≥3, there is a finite p-group G of exponent pn containing a quasinormal subgroup H of exponent pn−1 such that the nontrivial quasinormal subgroups of G lying in H can have ...

Pseudospectra of holographic quasinormal modes
Journal of High Energy Physics, 2023 Abstract Quasinormal modes and frequencies are the eigenvectors and eigenvalues of a non-Hermitian differential operator. They hold crucial significance in the physics of black holes. The analysis of quasinormal modes of black holes in asymptotically Anti-de Sitter geometries plays also a key role in the study of strongly coupled ...

Dual of Modulation Spaces with Variable Smoothness and Integrability
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In this article, we first give a proof for the denseness of the Schwartz class in the modulation spaces with variable smoothness and integrability. Then, we study the dual spaces of such modulation spaces.

Method of Lagrange Multipliers for Normalized Zero Norm Minimization
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 We present a normalization of the p‐norm. A compressive sensing criterion is proposed using the normalized zero norm. Based on the method of Lagrange multipliers, we derive the solution of the proposed optimization framework. It turns out that the new solution is a limit case of the least fractional norm solution for p = 0, where its fixed‐point ...

Countable Additivity of Spreading the Differentiation Operator
Моделирование и анализ информационных систем, 2014 In this article, we continue the study of the properties acquired by the differentiation operator Λ with spreading beyond the space W1¹. The study is conducted by introducing the family of spaces Yp¹ , 0 < p < 1, having analogy with the family Wp¹,
