On the ideals of extended quasi-nilpotent Banach algebras
International Journal of Mathematics and Mathematical Sciences, 1991 Given a quasi-nilpotent Banach algebra A, we will use the results of Seddighin [2], to study the properties of elements which belong to a proper closed two sided ideal of A¯ and A¯¯. Here A¯ is the extension of A to a Banach Algebra with identity.

Solid Mechanics Segregated Solver Acceleration With Jacobian‐Free Newton‐Krylov
International Journal for Numerical Methods in Engineering, Volume 127, Issue 11, 15 June 2026.ABSTRACT The segregated algorithm is a common approach for finite volumes solvers in solid mechanics, providing a memory‐efficient and straightforward implementation. Due to the inter‐coupling of the components through the source terms, it suffers from a slow convergence behavior in specific scenarios, such as geometries with significantly uneven ...

Fixed point characterization of left amenable Lau algebras
International Journal of Mathematics and Mathematical Sciences, 2004 The present paper deals with the concept of left amenability for a wide range of Banach algebras known as Lau algebras. It gives a fixed point property characterizing left amenable Lau algebras 𝒜 in terms of left Banach 𝒜-modules.

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics
Mathematical Methods in the Applied Sciences, Volume 49, Issue 9, Page 9696-9708, June 2026.ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

A Note on Amenability Modulo an Ideal of Unitial Banach Algebras
Journal of Mathematical Extension, 2015 In this paper we are continuing the study of the concept of amenability modulo an ideal of Banach algebras which is an extension of the usual notion of amenability.

ON DERIVATIONS IN BANACH ALGEBRAS
Bulletin of the Korean Mathematical Society, 2002 The authors prove that: (i) The only Jordan derivations \(D\) and \(G\) on a non-commutative \((n+1)!\) torsion free prime ring \(R\) such that \(D(x)x^n-x^nG(x)\) is in the center of \(R\) for all \(x\in R\) are \(D=0\) and \(G=0\); (ii) The only derivation \(D\) on a non-commutative 2-torsion free prime ring \(R\) such that the mapping \(x\rightarrow

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks
Mathematical Methods in the Applied Sciences, Volume 49, Issue 8, Page 8095-8117, 30 May 2026.ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

Strictly Cyclic Functionals, Reflexivity, and Hereditary Reflexivity of Operator Algebras
Abstract and Applied Analysis, 2012 This paper is concerned with strictly cyclic functionals of operator algebras on Banach spaces. It is shown that if X is a reflexive Banach space and A is a norm-closed semisimple abelian subalgebra of B(X) with a strictly cyclic functional f∈X∗, then A ...

Stability of multipliers on Banach algebras
International Journal of Mathematics and Mathematical Sciences, 2004 Suppose A is a Banach algebra without order. We show that an approximate multiplier T:A→A is an exact multiplier. We also consider an approximate multiplier T on a Banach algebra which need not be without order.
