On Commutativity Theorems for Rings [PDF]

open access: yesSoutheast Asian Bulletin of Mathematics, 2002
The author presents three commutativity theorems for rings. There are no rings satisfying the hypotheses of the first, and the second is trivial. The third, which asserts that a ring with 1 is commutative if it satisfies the identity \((x+y)^2=x^2+y^2\) and another extraneous hypothesis, is not new. In fact, \textit{C.-T.

An Augmented Lagrangian Preconditioner for Navier–Stokes Equations With Runge–Kutta in Time

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 3, June 2026.
ABSTRACT We consider an implicit Runge–Kutta method for the numerical time integration of the nonstationary incompressible Navier–Stokes equations. This yields a sequence of nonlinear problems to be solved for the stages of the Runge–Kutta method. The resulting nonlinear system of differential equations is discretized using a finite element method.

N-ideals of commutative rings

open access: yesFilomat, 2017
In this paper, we present a new classes of ideals: called n-ideal. Let R be a commutative ring with nonzero identity. We define a proper ideal I of R as an n-ideal if whenever ab ? I with a ? ?0, then b ? I for every a,b ? R. We investigate some properties of n-ideals analogous with prime ideals. Also, we give many examples with regard to n-

Excitonic Theory of the Ultrafast Optical Response of 2D‐Quantum‐Confined Semiconductors at Elevated Densities

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
In this work, an excitonic many‐body theory for the ultrafast optical response at elevated excitation densities for Wannier–Mott excitons is developed and applied to two distinct materials (GaAs quantum well and MoSe2 monolayer) as proponents of two different Coulomb‐interaction regimes.

Quantum Information Processing in Human Cognition: Bridging Quantum Phenomena, Neural Dynamics, and Decision‐Making

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
ABSTRACT Recent advances at the intersection of quantum physics, neuroscience, and cognitive science have renewed interest in whether quantum phenomena and quantum‐inspired formalisms can inform models of human cognition and decision‐making. While classical neural and computational models explain many aspects of perception and behavior, they face ...

A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

open access: yesSoftware: Practice and Experience, Volume 56, Issue 6, Page 643-657, June 2026.
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.
