| Abstract: | Some posets of binary leaf-labeled trees are shown to be supersolvable lattices and explicit EL-labelings are given. Their characteristic polynomials are computed, recovering their known factorization in a different way. |
| Keywords: | Supersolvable lattice Shellability Charateristic polynomial |
