Abstract

A molecular structure descriptor(topological descriptor) is numerical value associated with chemical construction for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. The topological descriptors are very important role in mathematical chemistry, especially, they are used in the studies of QSAR/QSPR: In this paper, we study the H-invariant of edge version of new join graphs.
