Canonical Basis Linearity Regions
Arising from Quiver Representations
ABSTRACT: (Joint work with M. Reineke (Wuppertal)). We consider the link between the
combinatorics of the canonical basis of a quantized enveloping algebra and
the monomial bases of M. Reineke arising from representations of quivers.
It will be seen how some reparametrization functions of the canonical basis,
arising from the link between Lusztig's approach to the canonical basis and
the string parametrization of the canonical basis, are given on a large region
of linearity by linear functions arising from these monomial bases for a
quantized enveloping algebra.
