Junction Type Representations of the Temperley-Lieb Algebra and Associated Symmetries

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
Inspired by earlier works on representations of the Temperley-Lieb algebra we introduce a novel family of representations of the algebra. This may be seen as a generalization of the so called asymmetric twin representation.

On Representations of sl(n, C) Compatible with a Z2-grading

open access: yesActa Polytechnica, 2010
This paper extends existing Lie algebra representation theory related to Lie algebra gradings. The notion of a representation compatible with a given grading is applied to finite-dimensional representations of sl(n,C) in relation to its Z2-gradings.

Ring homomorphisms on real Banach algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
Let B be a strictly real commutative real Banach algebra with the carrier space ΦB. If A is a commutative real Banach algebra, then we give a representation of a ring homomorphism ρ:A→B, which needs not be linear nor continuous.

Algebras of right ample semigroups

open access: yesOpen Mathematics, 2018
Strict RA semigroups are common generalizations of ample semigroups and inverse semigroups. The aim of this paper is to study algebras of strict RA semigroups.

On the geometry underlying a real Lie algebra representation [PDF]

open access: yes, 2012
Let $G$ be a real Lie group with Lie algebra $\mathfrak g$. Given a unitary representation $\pi$ of $G$, one obtains by differentiation a representation $d\pi$ of $\mathfrak g$ by unbounded, skew-adjoint operators.

Quantum groups, Yang–Baxter maps and quasi-determinants

open access: yesNuclear Physics B, 2018
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang–Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

The Lie algebra cohomology of jets

open access: yes, 2002
Let g be a finite-dimensional complex semi simple Lie algebra. We present a new calculation of the continuous cohomology of the Lie algebra z g[[z]]. In particular, we shall give an explicit formula for the Laplacian on the Lie algebra cochains, from ...

Spin one matter fields

open access: yesEuropean Physical Journal C: Particles and Fields
It is shown how spin one vector matter fields can be coupled to a Yang–Mills theory. Such matter fields are defined as belonging to a representation R of this Yang–Mills gauge algebra $$\mathfrak {g}$$ g .

Representation theory of solitons

open access: yesJournal of High Energy Physics
Solitons in two-dimensional quantum field theory exhibit patterns of degeneracies and associated selection rules on scattering amplitudes. We develop a representation theory that captures these intriguing features of solitons.
