Combinatorial properties of root systems of Lie (super)algebras.
Friday 27th October, 12-1pm, Carslaw 275.We discuss the normal orderings on the root systems of the contragredient Lie algebras and Lie superalgebras. These will be used in the constructions of quantum Cartan-Weyl bases, the extremal projections and universal R-matrices for quantum groups.
