RESUMO

Spectral Graph Theory (SGT) studies graph properties by graph representation matrix and its spectrum. A property from SGT, the eigencentrality, provides an important invariant to Graph Isomorphism Problem: if two graphs are isomorphic, they have proportional eigencentralities. However, this property can not be directly used for solving the Regular Graph Isomorphism Problem (RGIP), as every regular graph has the same eigencentralities. This work presents a strategy for solving the RGIP through the use of eigencentralities to prune the search tree and restricting the possibilities for mapping
