On the strong beta-number of galaxies with three and four components
The beta-number of a graph is the smallest positive integer for which there exists an injective function such that each is labeled and the resulting set of edge labels is for some positive integer . The beta-number of is if there exists no such integer . If , then the resulting beta-number is called...
