On complete systems of invariants for small graphs

open access: yesInternational Journal of Computer Mathematics, 1997
We define a small graph to be one with n ≤ 6 nodes. The celebrated Graph Isomorphism Problem (GIP) consists in deciding whether or not two given graphs are isomorphic, i.e., whether there is a bijective mapping from the nodes of one graph onto those of the other such that adjacency is preserved.

Some Invariants of Cartesian Product of a Path and a Complete Bipartite Graph [PDF]

open access: yesInternational Journal of Discrete Mathematics, 2019
A topological index of graph G is a numerical parameter related to G, which characterizes its topology and is preserved under isomorphism of graphs. Properties of the chemical compounds and topological indices are correlated. In this paper we will compute M-polynomial, first and second Zagreb polynomials and forgotten polynomial for the Cartesian ...

A three-colour graph as a complete topological invariant for gradient-like diffeomorphisms of surfaces

Sbornik Mathematics, 2014
In a paper of Oshemkov and Sharko, three-colour graphs were used to make the topological equivalence of Morse-Smale flows on surfaces obtained by Peixoto more precise. In the present paper, in the language of three-colour graphs equipped with automorphisms, we obtain a complete (including realization) topological classification of gradient-like ...
