F-coindex of some corona products of graphs

Abstract

The present-day trend of the numerical coding of chemical structures with topological indices or topological coindices have established quite successful in medicinal chemistry and bioinformatics. Topological indices and topological coindices can be used to look for (QSAR) and (QSPR), which are models that associate chemical structure with biological activity. One of the most important applications of the topological coindices is called F-coindex. In other side, some important classes of graphs can be obtained by corona products. In this paper, we compute the F-coindex of some corona products of two graphs such as corona product (vertex corona product), edge corona product, subdivision-vertex corona, subdivision-edge corona, vertex-edge corona, subdivision-vertex neighborhood corona and subdivision-edge neighborhood corona.
