The Adherence Order on Renner-Coxeter Monoids
  Building upon the previous Renner-Coxeter system of work by Eddy Godelle we introduce the familiar Renner monoid structure of the Adherence order. The Green's relations of the system are then considered in relation to the Adherence order and in the finite case maximum and minimum elements in each equivalence class are distinguished and studied.
