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.
