Abstract
The comaximal graph Σ(R) of a commutative ring R is a simple graph with vertex set R and two distinct vertices u and v of Σ(R) are adjacent if and only if uR + vR = R. In this paper, we find the sharp bounds for the Sombor index for comaximal graphs of integer modulo ring ℤn and give the corresponding extremal graphs. Also, we find the Sombor eigenvalues and the bounds for the Sombor energy of comaximal graphs of ℤn.
