Verma modules and preprojective algebras
Christof Geiss, Bernard Leclerc, Jan Schröer
We give a geometric construction of the Verma modules of a symmetric Kac-Moody Lie algebra in terms of constructible functions on the varieties of nilpotent finite-dimensional modu…

Semicanonical bases and preprojective algebras
Christof Geiss, Bernard Leclerc, Jan Schröer
We study the multiplicative properties of the dual of Lusztig's semicanonical basis.The elements of this basis are naturally indexed by theirreducible components of Lusztig's nilpo…

A Littlewood-Richardson rule for evaluation representations of quantum affine sl(n)
Bernard Leclerc
We give a combinatorial description of the composition factors of the induction product of two evaluation modules of the affine Iwahori-Hecke algebra of type GL(m). Using quantum a…
