HIGHLIGHTS
- who: Mathematics Subject Classification and colleagues from the Department of, Government Arts College (Autonomous), Kumbakonam, India have published the Article: A note on the symmetric division deg coindex of graphs, in the Journal: (JOURNAL)
- what: In this paper upper bounds on the symmetric division deg coindex of edge corona product of two graphs and Mycielskian of a graph are presented.
SUMMARY
The first Zagreb index and its coindex of a connected graph G are defined as X M1 (G)=(dG (u) + dG (v)) uv∈E(G) and M 1 (G)= X . . .
