Vnr-GRAPHS ASSOCIATED WITH RINGS
Let Rbe a finite commutative ring with nonzero identity. The Vnr-graph of R, denoted by has its set of vertices equal to the set of all elements of R; distinct vertices xand yare adjacent if and only if xyis a Von Neumann regular element of R. In this article, the basic properties of are investigated and some characterization results regarding connectedness, diameter, girth and planarity of are given.
