Abstract
In Chemical Graph Theory, several degree based topological indices were introduced and studied since 1972. Recently, Gutman considered a class of novel graph invariants of which the Sombor index was defined. In this paper, we introduce some new Sombor indices: the second, third, fourth and neighborhood (or fifth) Sombor indices of a graph. Furthermore, we compute the Sombor and neighborhood Sombor indices and their exponentials of some important nanostructures which appeared in nanoscience.
