Canonical Bases and Piecewise-linear Combinatorics
Roger Carter, Bethany Marsh
Let U be the quantum group associated to a Lie algebra g of rank n. The negative part U^- of U has a canonical basis B with favourable properties, introduced by Kashiwara and Luszt…

Regions of linearity, Lusztig cones and canonical basis elements for the quantized enveloping algebra of type A_4
Roger Carter, Bethany Marsh
Let U_q be the quantum group associated to a Lie algebra g of rank n. The negative part U^- of U has a canonical basis B with favourable properties, introduced by Kashiwara and Lus…
