The Diameter of a Zero-Divisor Graph for Finite Direct Product of Commutative Rings

Sarajevo Journal of Mathematics
This paper establishes a set of theorems that describe the diameter of a zero-divisor graph for a finite direct product$R_{1}\times R_{2}\times\cdots\times R_{n}$ with respect to the diameters of the zero-divisor graphs of $R_{1},R_{2},\cdots,R_{n-1 ...
