Abstract
The l-generalized quasi tree is a graph G for which we can find (Formula presented.) with (Formula presented.) such that (Formula presented.) is a tree but for an arbitrary (Formula presented.) with (Formula presented.), (Formula presented.) 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).
