چکیده
|
Let g = (v,e) be a finite simple graph. the sombor index so(g) of g is defined as σuvϵe(g)√ d^2 u + d^2v, where du is the degree of vertex u in g. in this paper, we study this index for certain graphs and we examine the effects on so(g) when g is modified by operations on vertex and edge of g. also we present bounds for the sombor index of join and corona product of two graphs.
