Self-Diagonal Tensor Powers of Quantum Groups and R-Matrices for Tensor Products of Representations

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/153344Twisted tensor powers of quasitriangular Hopf algebras with diagonal sub-Hopf-algebras (self-diagonal tensor powers) are introduced together with their duals and their mutual *-structures as generalizations of the Drinfel'd double as given by Reshetikhin and Semenov-Tian-Shansky. R-Matrices for tensor products of representations are derived.8 pages, latexQuantum AlgebraSelf-Diagonal Tensor Powers of Quantum Groups and R-Matrices for Tensor Products of Representationstext
