Combinatorial properties of root systems
of Lie (super)algebras.
Friday 27th October, 121pm, 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 CartanWeyl bases, the extremal projections and universal
Rmatrices for quantum groups.
