Quasi-tilted property of generalized lower triangular matrix algebras

Electronic Research Archive
In this paper, we investigated the generalized lower triangular matrix algebra, and gave the sufficient and necessary condition for the generalized lower triangular matrix algebra to be quasi-tilted.

On Generalized Transitive Matrices

Journal of Applied Mathematics, 2011
Transitivity of generalized fuzzy matrices over a special type of semiring is considered. The semiring is called incline algebra which generalizes Boolean algebra, fuzzy algebra, and distributive lattice.

Generalized Munn rings

Open Mathematics, 2022
Generalized Munn rings exist extensively in the theory of rings. The aim of this note is to answer when a generalized Munn ring is primitive (semiprimitive, semiprime and prime, respectively).

A model of quantum gravity with emergent spacetime

Journal of High Energy Physics, 2020
We construct a model of quantum gravity in which dimension, topology and geometry of spacetime are dynamical. The microscopic degree of freedom is a real rectangular matrix whose rows label internal flavours, and columns label spatial sites. In the limit

Generalized Jordan N-Derivations of Unital Algebras with Idempotents

Journal of Mathematics, 2021
Let A be a unital algebra with idempotent e over a 2-torsionfree unital commutative ring ℛ and S:A⟶A be an arbitrary generalized Jordan n-derivation associated with a Jordan n-derivation J.

Braided m-Lie Algebras

, 2003
Braided m-Lie algebras induced by multiplication are introduced, which generalize Lie algebras, Lie color algebras and quantum Lie algebras. The necessary and sufficient conditions for the braided m-Lie algebras to be strict Jacobi braided Lie algebras ...

On spectral spread of generalized distance matrix of a graph [PDF]

Linear and multilinear algebra, 2019
For a simple connected graph G, let , , and , respectively, are the distance matrix, the diagonal matrix of the vertex transmissions, distance Laplacian matrix and the distance signless Laplacian matrix. The generalized distance matrix of G is the convex

Completeness of Bethe ansatz for Gaudin models associated with gl(1|1)

Nuclear Physics B, 2022
We study the Gaudin models associated with gl(1|1). We give an explicit description of the algebra of Hamiltonians (Gaudin Hamiltonians) acting on tensor products of polynomial evaluation gl(1|1)[t]-modules.

On generators of abelian Kadison–Singer algebras in matrix algebras

Linear Algebra and its Applications, 2014
Let \(\mathcal H\) be a Hilbert space of dimension greater than two and let \(\mathcal B(\mathcal H)\) be the algebra of all bounded linear operators on \(\mathcal H\). A subalgebra \(\mathfrak A\) of \(\mathcal B(\mathcal H)\) is called a Kadison-Singer algebra (or KS-algebra) if \(\mathfrak A\) is reflexive and maximal with respect to the diagonal ...
