Classical R-Operators and Integrable Generalizations of Thirring Equations
We construct different integrable generalizations of the massive Thirring equations corresponding loop algebras g^σ in different gradings and associated ''triangular'' R-operators.

The Characterization of Generalized Jordan Centralizers on Triangular Algebras
In this paper, it is shown that if T=Tri(A,M,B) is a triangular algebra and ϕ is an additive operator on T such that (m+n+k+l)ϕ(T2)-(mϕ(T)T+nTϕ(T)+kϕ(I)T2+lT2ϕ(I))∈FI for any T∈T, then ϕ is a centralizer. It follows that an (m,n)- Jordan centralizer on a

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

On Jordan triple (σ,τ)-higher derivation of triangular algebra
Let R be a commutative ring with unity, A = Tri(A,M,B) be a triangular algebra consisting of unital algebras A,B and (A,B)-bimodule M which is faithful as a left A-module and also as a right B-module.

Higher-n triangular dilatonic black holes
Dilaton gravity with the form fields is known to possess dyon solutions with two horizons for the discrete “triangular” values of the dilaton coupling constant a=n(n+1)/2.

Triangular Decomposition of the Composition Algebra of the Kronecker Algebra
Let \(K\) be a finite field and let \(R\) be a finite dimensional \(K\)-algebra. Denote by \(S_1,\ldots,S_n\) a complete set of pairwise non-isomorphic simple right \(R\)-modules. Given a finite right \(R\)-module \(M\) we denote by \(\mathbf{dim} M=(m_1,\dots,m_n)\) the dimension vector of \(M\) in \(\mathbb{Z}^n\), that is the coordinate \(m_j\) is ...

Sigma-maps on triangular algebras
Triangular algebras were introduced by Chase in the early 1960s. He ended up with these structures in the course of his study of the asymmetric behavior of semi-hereditary rings.

ABSTRACT In this work, a new event‐triggered adaptive first‐order sliding mode control method is proposed for nonlinear systems with constant time delays, modeled by interval type‐2 Takagi–Sugeno (T–S) fuzzy systems. To handle matched disturbances with unknown upper bounds, a non‐overestimating adaptation strategy for the control coefficient is ...

Cyclic amenability of Lau product and module extension Banach algebras
Introduction The notion of weak amenability for commutative Banach algebras was introduced and studied for the first time by Bade, Curtis and Dales. Johnson extended this concept to the non commutative case and showed that group algebras of all locally ...

Sliding Mode Control in Aerospace Applications: A Survey
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
