چکیده | ||
The Sombor index is a vertex degree-based topological index which it was de ned by Ivan Gutman in 2021. We study the Sombor index and the multiplicative Sombor index on some products of graphs, crown graphs, shelf graphs, Ice-cream graphs, helm graphs, ower graphs, generalized Sierpiński graphs, $t$-Mycielskian graphs, $t$-ciclo graphs, and $t$-estella graphs. Then we provide some upper and lower bounds for them. | ||
