On Ulam’s conjecture for separable graphs

J. Adrian (John) Bondy

Vol. 31 (1969), No. 2, 281–288
Abstract

Ulam’s conjecture, that every graph of order greater than two is determined up to isomorphism by its collection of maximal subgraphs, is verified for the case of separable graphs which have no pendant vertices. Partial results are then obtained for the case of graphs with pendant vertices.
