Résumé : It is shown how edge effects in monomer-dimer mixtures on the square lattice can be obtained by means of the strong lattice constants of a particular graph. Series expansions of the edge tension and adsorption are given up to the sixth power in the dimer density. The subsequent analysis shows that these series are still too short to account for the actual value of the edge tension of a pure dimer assembly derived by Fisher and Ferdinand. © 1970.
