GENERALIZED IRREDUCIBLE DIVISOR GRAPHS

In 1988, Beck introduced the notion of a zero-divisor graph of a commutative rings with 1. There have been several generalizations in recent years. In particular, in 2007 Coykendall and Maney developed the irreducible divisor graph. Much work has been done on generalized factorization, especially tau-factorization. The goal of this paper is to synthesize the notions of tau-factorization and irreducible divisor graphs in domains. We will define a tau-irreducible divisor graph for nonzero non unit elements of a domain. We show that, by studying tau-irreducible divisor graphs, we find equivalent characterizations of several finite tau-factorization properties.
