A positive basis for surface skein algebras

Geometric Topology 2016-11-03 v2 Combinatorics Rings and Algebras

Abstract

We show that the twisted SL(2) skein algebra of a surface has a natural basis (the bracelets basis) that is positive, in the sense that the structure constants for multiplication are positive integers.
