Coxeter Pop-Tsack Torsing

Colin Defant, Nathan Williams

Given a finite irreducible Coxeter group $W$ with a fixed Coxeter element $c$ , we define the Coxeter pop-tsack torsing operator $Pop_{T} : W \to W$ by $\mathsf{Pop}_T(w)=w\cdot…

Pop-Stack-Sorting for Coxeter Groups

Colin Defant

Let $W$ be an irreducible Coxeter group. We define the Coxeter pop-stack-sorting operator $Pop : W \to W$ to be the map that fixes the identity element and sends each noniden…

Postorder Preimages

Colin Defant

Given a set $Y$ of decreasing plane trees and a permutation $π$ , how many trees in $Y$ have $π$ as their postorder? Using combinatorial and geometric constructions, we provide a me…
