Seminario del 09 de noviembre

09/11/2017, 16.00 hs, aula 27 FaMAF Hopf algebras having a dense big cell Expositor: Julien Bichon Resumen: We will discuss some axioms that ensure that a quantum goup has its irreducible representations classified by means of an analogue of the Borel-Weil construction. The axioms are inspired by the work of Parshall-Wang for the usual q-deformation …
