Ordering Unicyclic Graphs with Respect to F-index
Ruhul Amin, Sk. Md. Abu Nayeem
F-index of a graph is the sum of the cube of the degrees of the vertices. In this paper, we investigate the F-indices of unicyclic graphs by introducing some transformation, and ch…

On the F-index and F-coindex of the line graphs of the subdivision graphs
Ruhul Amin, Sk. Md. Abu Nayeem
The aim of this work is to investigate the F-index and F-coindex of the line graphs of the cycle graphs, star graphs, tadpole graphs, wheel graphs and ladder graphs using the subdi…
