Permutations whose reverse shares the same recording tableau in the RSK correspondence

Tucker J. Ervin, Blake Jackson, Jay Lane +4

The RSK correspondence is a bijection between permutations and pairs of standard Young tableaux with identical shape, where the tableaux are commonly denoted (insertion) and $Q…

Mutations of reflections and existence of pseudo-acyclic orderings for type

Tucker J. Ervin, Blake Jackson, Kyu-Hwan Lee +1

In a recent paper by K.-H. Lee, K. Lee and M. Mills, a mutation of reflections in the universal Coxeter group is defined in association with a mutation of a quiver. A matrix repres…

Rigid reflections and Kac--Moody algebras

Kyu-Hwan Lee, Kyungyong Lee

Given any Coxeter group, we define rigid reflections and rigid roots using non-self-intersecting curves on a Riemann surface with labeled curves. When the Coxeter group arises from…

A correspondence between rigid modules over path algebras and simple curves on Riemann surfaces

Kyu-Hwan Lee, Kyungyong Lee

We propose a conjectural correspondence between the set of rigid indecomposable modules over the path algebras of acyclic quivers and the set of certain non-self-intersecting curve…

A combinatorial approach to root multiplicities of rank 2 hyperbolic Kac-Moody algebras

Seok-Jin Kang, Kyu-Hwan Lee, Kyungyong Lee

In this paper we study root multiplicities of rank 2 hyperbolic Kac-Moody algebras using the combinatorics of Dyck paths.
