On the irreducibility of an induced representation [PDF]
Pacific Journal of Mathematics, 1981 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.

Irreducible Representations of Algebras [PDF]
Canadian Journal of Mathematics, 1974 The concept of the universal enveloping algebra of a (not necessarily associative) algebra X is basic to the study of the representations of X, because there is a one-to-one correspondence between the representations of X and . If one is only interested in studying a certain class of the representations of X, the thought occurs that there may exist a ...

A classification of irreducible admissible mod p representations of p-adic reductive groups [PDF]
, 2014 Let F be a locally compact non-archimedean field, p its residue characteristic, and G a connected reductive group over F. Let C an algebraically closed field of characteristic p.

Irreducible Modular Representations of the Reflection Group G(m,1,n)
Journal of Mathematics, 2015 In an article published in 1980, Farahat and Peel realized the irreducible modular representations of the symmetric group. One year later, Al-Aamily, Morris, and Peel constructed the irreducible modular representations for a Weyl group of type Bn.

Noetherianity of the space of irreducible representations [PDF]
Israel Journal of Mathematics, 2003 Let R be an associative ring with identity. We study an elementary generalization of the classical Zariski topology, applied to the set of isomorphism classes of simple left R-modules (or, more generally, simple objects in a complete abelian category).

Extended Poincar\'e supersymmetry in three dimensions and supersymmetric anyons [PDF]
, 2012 We classify the unitary representations of the extended Poincar\'e supergroups in three dimensions. Irreducible unitary representations of any spin can appear, which correspond to supersymmetric anyons.

Multipartite Quantum Systems and Representations of Wreath Products [PDF]
EPJ Web of Conferences, 2020 The multipartite quantum systems are of particular interest for the study of such phenomena as entanglement and non-local correlations. The symmetry group of the whole multipartite system is the wreath product of the group acting in the “local” Hilbert ...

Isotropy irreducible spaces and s-representations
Differential Geometry and its Applications, 1996 A homogeneous space \(G/K\) is called isotropy irreducible if the action of the isotropy group \(K\) on its tangent space is irreducible. Classical examples are the irreducible symmetric spaces. The non-symmetric isotropy irreducible spaces with \(K\) compact and connected have been classified by O. V. Manturov and J. A. Wolf.

Irreducible representations of Leavitt path algebras [PDF]
, 2011 We construct some irreducible representations of the Leavitt path algebra of an arbitrary quiver. The constructed representations are associated to certain algebraic branching systems.
