Podleś' Quantum Sphere: Dual Coalgebra and Classification of Covariant First Order Differential Calculus

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/63877The dual coalgebra of Podleś' quantum sphere O_q(S^2_c) is determined explicitly. This result is used to classify all finite dimensional covariant first order differential calculi over O_q(S^2_c) for all but exceptional values of the parameter c.LaTeX2e, 19 pagesQuantum Algebra58B32, 81R50Podleś' Quantum Sphere: Dual Coalgebra and Classification of Covariant First Order Differential Calculustext
