Generalized Temperley–Lieb Diagrams and the Mathas–Lusztig Involution
This page explores the Mathas–Lusztig involution on Fully Commutative elements of Coxeter systems. In particular, it realizes such elements as diagrams: elements of Generalized Temperley–Lieb algebras. On the page corresponding to each Coxeter system, the "canonical diagrams" associated to each FC-element pair are displayed side-by-side. Each page includes filtering functionality, and the option to display only pairs of elements that actually differ under the involution.
