New Results on the Forgotten Topological Index and Coindex
The ℱ-coindex (forgotten topological coindex) for a simple connected graph G is defined as the sum of the terms ζG2y+ζG2x over all nonadjacent vertex pairs x,y of G, where ζGy and ζGx are the degrees of the vertices y and x in G, respectively. The ℱ-index of a graph is defined as the sum of cubes of...
