We prove the equivalence of EL-shellability and the existence of recursive atom ordering independent of roots. We show that a comodernistic lattice, as defined by Schweig and Woodroofe, admits a recursive atom ordering independent of roots,…
We construct an ungraded CL-shellable poset and a graded CL-shellable poset and show that neither is EL-shellable.
