Abstract

Molecular graphs able to model covalent multiple bonds are called plerographs. For such graphs, with single, double and triple edges, compact degree sequences (n(1), n(2), n(3), n(4)), where n(i), i = 1, 2, 3, 4 denote the number of vertices of degree i, are defined. Investigations are extended to necessary and sufficient conditions on (n(1), n(2), n(3), n(4)) for the existence of graph G such that G has n(1), n(2), n(3) and n(4) vertices of degrees 1, 2, 3 and 4. Namely, graphs with non-trivial cycles with at least three vertices are allowed.
