BasisGen: automatic generation of operator bases
European Physical Journal C: Particles and Fields, 2019 BasisGen is a Python package for the automatic generation of bases of operators in effective field theories. It accepts any semisimple symmetry group and fields in any of its finite dimensional irreducible representations.

Irreducible representations of crossed products
Journal of Pure and Applied Algebra, 1998 In 1975, I. Kaplansky conjectured that if \(H\) is a finite-dimensional semisimple Hopf algebra over an algebraically closed field, then the dimension of each irreducible \(H\)-module divides the dimension of \(H\). The main result of this paper is a verification of this conjecture for fields of characteristic 0 and Hopf algebras of prime power ...

On irreducible representations of the exotic conformal Galilei algebra [PDF]
, 2010 We investigate the representations of the exotic conformal Galilei algebra. This is done by explicitly constructing all singular vectors within the Verma modules, and then deducing irreducibility of the associated highest weight quotient modules.

Representations of the q-deformed algebra $U_q({\rm iso}_2)$
, 1999 An algebra homomorphism $\psi$ from the q-deformed algebra $U_q({\rm iso}_2)$ with generating elements $I$, $T_1$, $T_2$ and defining relations $[I,T_2]_q=T_1$, $[T_1,I]_q=T_2$, $[T_2,T_1]_q=0$ (where $[A,B]_q=q^{1/2}AB-q^{-1/2}BA$) to the extension ...

SciPost Physics Lecture NotesWe revisit the classifications of classical and quantum galilean particles: that is, we fully classify homogeneous symplectic manifolds and unitary irreducible projective representations of the Galilei group.

ON GENERALIZATION OF SPECIAL FUNCTIONS RELATED TO WEYL GROUPS
Acta Polytechnica, 2016 Weyl group orbit functions are defined in the context of Weyl groups of simple Lie algebras. They are multivariable complex functions possessing remarkable properties such as (anti)invariance with respect to the corresponding Weyl group, continuous and ...

, 1999 The minimal irreducible representations of $U_q[gl(m|n)]$, i.e. those irreducible representations that are also irreducible under $U_q[osp(m|n)]$ are investigated and shown to be affinizable to give irreducible representations of the twisted quantum ...

On irreducible projective representations of finite groups [PDF]
Surveys in Mathematics and its Applications, 2009 The paper is a survey type article inwhich we present some results on irreducible projective representations offinite groups. Section 2 includes Curtis and Reiner's theorem inwhich is proved that a finite group has at most a finite number ofinequivalent ...

On the irreducibility of an induced representation. II [PDF]
Proceedings of the American Mathematical Society, 1982 A unitary representation induced from a normal subgroup of a separable locally compact group is irreducible if and only if the inducing representation is irreducible and the restriction of the induced representation to the normal subgroup is multiplicity-free.
