Construction of an algebra corresponding to a statistical model of the square ladder (square lattice with two lines)

open access: yesNuclear Physics B, 2022
In this paper we define infinite-dimensional algebra and its representation, whose basis is naturally identified with semi-infinite configurations of the square ladder model (square lattice with two lines). All these lead to representation of N=2 algebra.

Tame triangular matrix algebras [PDF]

open access: yesColloquium Mathematicum, 2000
Let \(A\) be a finite dimensional \(k\)-algebra for \(k\) algebraically closed, such that the triangular matrix algebra \(T_2(A)\) is tame. It is known that in this case, \(A\) is of finite representation type and standard. In this paper, the authors describe, in terms of full, convex subcategories of \(\widetilde A\) (the universal Galois covering of \

Approximate Biprojectivity of ℓ1-Munn Banach Algebras

open access: yesJournal of Mathematics, 2022
In the present paper, we study the approximate biprojectivity and weak approximate biprojectivity of ℓ1-Munn Banach algebras when the related sandwich matrix is regular over InvA.

Jordan automorphisms, Jordan derivations of generalized triangular matrix algebra

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We investigate Jordan automorphisms and Jordan derivations of a class of algebras called generalized triangular matrix algebras. We prove that any Jordan automorphism on such an algebra is either an automorphism or an antiautomorphism and any Jordan ...

Characteristic Polynomial and Eigenproblem of Triangular Matrix over Interval Min-Plus Algebra

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika)
A min-plus algebra is a linear algebra over the semiring R_ε', equipped with the operations “"⊕'=min" ” and “⊗=+”. In min-plus algebra, there is the concept of characteristic polynomial obtained from permanent of matrix.

Derivations of certain operator algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Let 𝒩 be a nest and let 𝒜 be a subalgebra of L(H) containing all rank one operators of alg 𝒩. We give several conditions under which any derivation δ from 𝒜 into L(H) must be inner.

n -Derivations of triangular algebras

open access: yesLinear Algebra and its Applications, 2013
Let \(\mathcal A\) be a triangular algebra. Let \(n\geq 2\) be an integer. A mapping \(\varphi\colon\mathcal A\times\mathcal A\times\cdots\times\mathcal A\to\mathcal A\) is said to be an \(n\)-derivation if it is a derivation in each argument. In this paper the authors mainly investigate \(n\)-derivations (\(n\geq 3\)) for a certain class of triangular

Involutive triangular matrix algebras

open access: yesHacettepe Journal of Mathematics and Statistics, 2020
In this paper we provide new examples of Banach $ \ast $-subalgebras of the matrix algebra $M_n(\mathscr{A}) $ over a commutative unital $C^*$-algebra $\mathscr{A}$. For any involutive algebra, we define two involutions on the triangular matrix extensions. We prove that the triangular matrix algebras over any commutative unital $C^*$-algebra

open access: yesCommentationes Mathematicae Universitatis Carolinae, 2015
Summary: We give a sufficient condition under which any Jordan automorphism of a triangular algebra is either an automorphism or an anti-automorphism.
