Solvable Leibniz algebras with triangular nilradicals [PDF]
, 2014 In this paper the description of solvable Lie algebras with triangular nilradicals is extended to Leibniz algebras. It is proven that the matrices of the left and right operators on elements of Leibniz algebra have upper triangular forms.

Limit algebras and integer-valued cocycles, revisited
, 2016 A triangular limit algebra A is isometrically isomorphic to the tensor algebra of a C*-correspondence if and only if its fundamental relation R(A) is a tree admitting a $Z^+_0$-valued continuous and coherent cocycle.

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

On Jordan triple (σ,τ)-higher derivation of triangular algebra
Special Matrices, 2018 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.

Some Results about Triangular Representations of Lie Algebras [PDF]
, 2014 We introduce the concept of a triangular representation of a Lie algebra, give a counterpart of Ado's theorem, and discuss $2$-irreducible triangular modules over a nonreductive Lie ...

Non-standard quantum so(3,2) and its contractions
, 1997 A full (triangular) quantum deformation of so(3,2) is presented by considering this algebra as the conformal algebra of the 2+1 dimensional Minkowskian spacetime.

Algebraic and Triangular n-Hyponormal Operators [PDF]
Proceedings of the American Mathematical Society, 1995 In this paper we shall prove that if an operator T ∈ L ( ⊕ 1 n H ) T \in \mathcal {L}( \oplus _1^n{\mathbf {H}}) is a finite triangular operator matrix with hyponormal operators on main diagonal, then T ...

Coordinates for triangular operator algebras. II [PDF]
Pacific Journal of Mathematics, 1989 Write \({\mathcal M}\) for the full algebra of complex \(n\times n\) matrices, \({\mathcal A}\) for its subalgebra of diagonal matrices, and \({\mathcal P}\) for the intermediate algebra of upper-triangular matrices. Fix \(\delta\) in \({\mathcal A}\) with strictly decreasing real diagonal entries and define a group of automorphisms of \({\mathcal M}\)

Unitary Irreducible Representations of a Lie Algebra for Matrix Chain Models
, 2001 There is a decomposition of a Lie algebra for open matrix chains akin to the triangular decomposition. We use this decomposition to construct unitary irreducible representations. All multiple meson states can be retrieved this way. Moreover, they are the
