| Abstract: |
In this paper we compute the correct values of Zagreb indices and the forgotten index of two classes of composite graphs "disjunction and symmetric difference". In this way we correct some previously reported formulas given in https://doi.org/10.1016/j.dam.2008.06.015 , https://doi.org/10.1016/j.dam.2010.05.017 and https://link.springer.com/article/10.1186/s40064-016-1864-7. As a consequence, we compute the correct values of the respective. • Give and prove the correct formulas of Zagreb indices and their coindices of symmetric difference. • Give and prove the correct formulas of Zagreb indices and their coindices of disjunction. • Give and prove the correct formulas of F-coindex of symmetric difference.
