摘要: In [1], Joe Warfel investigated the diameter of a zero-divisor graph for a direct product R1×R2 with respect to the diameter of the zero-divisor graph of R1 and R2. But the author only considered those graphs whose diameters ≥ 1 and discussed six cases. This paper further discusses the other nine cases and also gives a complete characterization for the possible diameters for left Artin rings.

Abstract: In [1], Joe Warfel investigated the diameter of a zero-divisor graph for a direct product R1×R2 with respect to the diameter of the zero-divisor graph of Rand R2. But the author only considered those graphs whose diameters ≥ 1 and discussed six cases. This paper further discusses the other nine cases and also gives a complete characterization for the possible diameters for left Artin rings.

Key words: zero-divisor graph, diameter, Artin ring, local ring
