2-roots for simply laced Weyl groups

R. M. Green, Tianyuan Xu

We introduce and study "2-roots", which are symmetrized tensor products of orthogonal roots of Kac--Moody algebras. We concentrate on the case where $W$ is the Weyl group of a simp…

Subregular $J$ -rings of Coxeter systems via quiver path algebras

Ivan Dimitrov, Charles Paquette, David Wehlau +1

We study the subregular $J$ -ring $J_{C}$ of a Coxeter system $(W, S)$ , a subring of Lusztig's $J$ -ring. We prove that $J_{C}$ is isomorphic to a quotient of the path algebra of the doub…
