Abstract

The l -generalized quasi tree is a graph G for which we can find W ⊂ V ( G ) with | W | = l such that G − W is a tree but for an arbitrary Y ⊂ V ( G ) with | Y | < l , G − Y is not a tree. In this paper, inequalities with respect to zeroth-order Randić and hyper-Zagreb indices are studied in the class of l -generalized quasi trees. The corresponding extremal graphs corresponding to these indices in the class of l -generalized quasi trees are also obtained. In addition, we carry QSPR analysis of COVID-19 drugs with zeroth-order Randić and hyper-Zagreb indices (energy).
