Multiplicative Jordan triple higher semi-derivations on rings and standard operator algebras

Annals of Mathematics and Computer Science
In this paper we study the additivity of multiplicative Jordan triple higher semi-derivations on rings and standard operator algebras.

Elements of rings and Banach algebras with related spectral idempotents

Journal of the Australian Mathematical Society, 2006
Let aπ denote the spectral idempotent of a generalized Drazin invertible element a of a ring. We characterize elements b such that 1 − (bπ − aπ)2 is invertible.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Two‐phase model for the excavation analysis in partially saturated soft soils using the particle finite element method

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 2, Page 145-186, 10 February 2023., 2023
Abstract A two‐phase velocity‐pressure stabilized formulation is proposed for the numerical analysis of mechanized excavations in partially saturated soft soils using the Particle Finite Element Method (PFEM). The fully coupled formulation is based on the theory of porous media in association with the Soil Water Characteristic Curve and the porosity ...

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

Advanced Theory and Simulations, EarlyView.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

Hochschild cohomology of group extensions of quantum symmetric algebras [PDF]

, 2010
Quantum symmetric algebras (or noncommutative polynomial rings) arise in many places in mathematics. In this article we find the multiplicative structure of their Hochschild cohomology when the coefficients are in an arbitrary bimodule algebra. When this

Surprising occurrences of order structures in mathematics

, 2023
Order and symmetry are main structural principles in mathematics. We give five examples where on the face of it order is not apparent, but deeper investigations reveal that they are governed by order structures.

P-jets of finite algebras. II: $p$-typical Witt rings

Documenta Mathematica, 2013
We study the structure of the p-jet spaces of the p-typical Witt rings of the p-adics. We also study the p-jets of the comonad map. These data can be viewed as an arithmetic analogue, for the ring Z, of the Lie groupoid of the line and hence as an ...

Vertex Algebras and Costello-Gwilliam Factorization Algebras [PDF]

arXiv, 2020
Vertex algebras and factorization algebras are two approaches to chiral conformal field theory. Costello and Gwilliam describe how every holomorphic factorization algebra on the plane of complex numbers satisfying certain assumptions gives rise to a Z-graded vertex algebra. They construct some models of chiral conformal theory as factorization algebras.

Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor

Advanced Electronic Materials, EarlyView.
This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...
