Abstract

Let GG be a simple graph with binomial edge ideal JGJ_G. We prove how to calculate the multidegree of JGJ_G based on combinatorial properties of GG. In particular, we study the set Smin(G)S_{\min}(G) defined as the collection of subsets of vertices whose prime ideals have minimum codimension. We provide results which assist in determining Smin(G)S_{\min}(G), then calculate Smin(G)S_{\min}(G) for star, horned complete, barbell, cycle, wheel, and friendship graphs, and use the main result of the paper to obtain the multidegrees of their binomial edge ideals.
