Finite Comparison Algebras for Motivic Projectors and Triangular Stability

Mathematics
We study a finite-stage criterion for representing auxiliary or motivated idempotents by ordinary motivic projectors. To a fixed finite list of operations on a motive M we attach a finite comparison algebra EΓ(M), a finite-dimensional ordinary comparison

Nonlinear generalized Jordan (σ, Γ)-derivations on triangular algebras

Special Matrices, 2018
Let R be a commutative ring with identity element, A and B be unital algebras over R and let M be (A,B)-bimodule which is faithful as a left A-module and also faithful as a right B-module.

White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

The Ribbon Elements of the Quantum Double of Generalized Taft–Hopf Algebra

Mathematics
Let s, t be two positive integers and k be an algebraically closed field with char (k)∤st. We show that the Drinfeld double D(⋀st,t*cop) of generalized Taft–Hopf algebra ⋀st,t*cop has ribbon elements if and only if t is odd.

More on Weak Amenability of Triangular Banach Algebras [PDF]

Sahand Communications in Mathematical Analysis
For two Banach algebras $A$ and $B$ and a Banach $(A,B)$-module $X$, let $\mathrm{Tri}(A,X,B)$ be the corresponding triangular Banach algebra. In this paper, among other things, we give some characterizations of $n$-weak amenability of $\mathrm{Tri}(A,X ...

Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Complexity of triangular representations of algebraic sets

Journal of Algebra, 2019
Triangular decomposition is one of the standard ways to represent the radical of a polynomial ideal. A general algorithm for computing such a decomposition was proposed by A. Szanto. In this paper, we give the first complete bounds for the degrees of the polynomials and the number of components in the output of the algorithm, providing explicit ...

Reducing acquisition time and radiation damage: data‐driven subsampling for spectro‐microscopy

Journal of Synchrotron Radiation, EarlyView.
Data‐driven sparse acquisition in spectro‐microscopy reduces acquisition time and radiation dose while preserving information.Spectro‐microscopy is an experimental technique which can be used to observe spatial variations in chemical state and changes in chemical state over time or under experimental conditions.

Involutions for upper triangular matrix algebras

Advances in Applied Mathematics, 2006
The first result in the paper under review is the description of the involutions of the first kind (which fix the centre) of the algebra \(UT_n(F)\) of \(n\times n\) upper triangular matrices over a field of characteristic different from 2. The authors show that, up to isomorphism of algebras with involution, there are two types of involutions.
