WebJan 1, 2024 · For a commutative ring R with non-zero zero-divisor set Z^* (R), the zero-divisor graph of R is \varGamma (R) with vertex set Z^* (R), where two distinct vertices x and y are adjacent if and only if xy=0. The zero-divisor graph structure of {\mathbb {Z}}_ {p^n} is described. We determine the clique number, degree of the vertices, size, metric ... WebFeb 18, 2024 · Preview Activity 1 (Definition of Divides, Divisor, Multiple, is Divisible by) In Section 3.1, we studied the concepts of even integers and odd integers. The definition of an even integer was a formalization of our concept of an even integer as being one this is “divisible by 2,” or a “multiple of 2.” We could also say that if “2 ...
