Residually reducible representations of algebras over local Artinian rings [PDF]

open access: yes, 2008
In this paper we generalize a result of Urban on the structure of residually reducible representations on local Artinian rings from the case that the semi-simplification of the residual representation splits into 2 absolutely irreducible representations ...

Degenerate Series Representations of the q-Deformed Algebra $so'_q(r,s)$

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The $q$-deformed algebra ${m so}'_q(r,s)$ is a realform of the $q$-deformed algebra $U'_q({m so}(n,mathbb{C}))$,$n=r+s$, which dif/fers from the quantum algebra $U_q({mso}(n,mathbb{C}))$ of Drinfeld and Jimbo.

Efficient operators for studying higher partial waves

open access: yesEPJ Web of Conferences, 2018
An extended multi-hadron operator is developed to extract the spectra of irreducible representations in the finite volume. The irreducible representations of the cubic group are projected using a coordinate-space operator.

Computing Irreducible Representations of Groups [PDF]

open access: yesMathematics of Computation, 1970
How can you find a complete set of inequivalent irreducible (ordinary) representations of a finite group? The theory is classical but, except when the group was very small or had a rather special structure, the actual computations were prohibitive before the advent of high-speed computers; and there remain practical difficulties even for groups of ...

Varieties of four-dimensional gauge theories

open access: yesJournal of High Energy Physics
We use algebraic geometry to study the anomaly-free representations of an arbitrary gauge Lie algebra for 4-dimensional spacetime fermions. For irreducible representations, the problem reduces to studying the Lie algebras 𝔰𝔲 n for n ≥ 3.

Symmetry algebra for the generic superintegrable system on the sphere

open access: yesJournal of High Energy Physics, 2018
The goal of the present paper is to provide a detailed study of irreducible representations of the algebra generated by the symmetries of the generic quantum superintegrable system on the d-sphere.

Irreducible decomposition for tensor prodect representations of Jordanian quantum algebras

open access: yes, 1997
Tensor products of irreducible representations of the Jordanian quantum algebras U_h(sl(2)) and U_h(su(1,1)) are considered. For both the highest weight finite dimensional representations of U_h(sl(2)) and lowest weight infinite dimensional ones of U_h ...

IRREDUCIBLE REPRESENTATIONS OF HILBERT C-MODULES [PDF]

open access: yesMathematical Proceedings of the Royal Irish Academy, 2005
The subject of the paper is representations of Hilbert C*-modules. We introduce the concept of a nondegenerate, irreducible and cyclic representation and the cornmutant of a Hilbert C*-module. Relations between representations of a Hilbert C*-module, its linking algebra and underlying C*-algebras are discussed. We also study Hilbert CCR-and GCR-modules
