Two remarks on decomposition numbers of standard modules for quantum affine
Xin Fang, Deniz Kus, Markus Reineke
We use Nakajima's geometric approach to representations of quantum affine algebras and recent results on explicit descriptions of specific canonical basis elements, to derive close…

Local intersection cohomology of varieties of complexes
Xin Fang, Markus Reineke
We compute the local intersection cohomology of the irreducible components of varieties of complexes, by using Lusztig's geometric approach to quantum groups and explicit construct…
