On the structure and representations of quantum graph algebras at roots of unity

Stéphane Baseilhac, Matthieu Faitg, Philippe Roche

We study the specializations at roots of unity of odd order of the graph algebras, associated to a simply-connected complex semi-simple algebraic group $G…

Noetherian and affine properties of quantum moduli and -skein algebras

Stéphane Baseilhac, Matthieu Faitg, Philippe Roche

We prove that the quantum moduli algebra associated to a possibly punctured compact oriented surface and a complex semisimple Lie algebra is a Noetherian and finitel…

Unrestricted Quantum Moduli Algebras, II: Noetherianity and Simple Fraction Rings at Roots of 1

Stéphane Baseilhac, Philippe Roche

We prove that the quantum graph algebra and the quantum moduli algebra associated to a punctured sphere and complex semisimple Lie algebra are Noetherian rings and f…

Generalized Zeta function representation of groups and 2-dimensional Topological Yang-Mills theory: The example of GL(2, F_q) and PGL(2, F_q)

Philippe Roche

We recall the relation between Zeta function representation of groups and two-dimensional topological Yang-Mills theory through Mednikh formula. We prove various generalisations of…
