Relations and bounds for the zeros of graph polynomials using vertex orbits

作者:

Highlights:

• We examine further the measure δ for measuring symmetry in networks.

• We establish bounds for δ for graphs with a given number of orbit sizes.

• These results can be used to classify graphs.

• We perform an analysis to explore symmetry on isomers.

• The analysis of the chemical graphs reveal that only a very few chemical graphs are highly symmetric.
