Combinatorics of canonical bases revisited: String data in type
Volker Genz, Gleb Koshevoy, Bea Schumann
We give a formula for the crystal structure on the integer points of the string polytopes and the -crystal structure on the integer points of the string cones of type for ar…
On the interplay of the parametrizations of canonical bases by Lusztig and string data
Volker Genz, Gleb Koshevoy, Bea Schumann
For arbitrary reduced words we give formulas for the crystal structures on string and Lusztig data of type A as well as the defining inequalities of the corresponding polytopes rev…
Polyhedral parametrizations of canonical bases & cluster duality
Volker Genz, Gleb Koshevoy, Bea Schumann
We establish the relation of the potential function constructed by Gross-Hacking-Keel-Kontsevich's and Berenstein-Kazhdan's decoration function on the open double Bruhat cell in th…
Combinatorics of canonical bases revisited: Type A
Volker Genz, Gleb Koshevoy, Bea Schumann
We initiate a new approach to the study of the combinatorics of several parametrizations of canonical bases. In this work we deal with Lie algebras of type . Using geometric obj…
