| Let G be a finite group. The commutativity degree of G, written d(G), is defined as the ratio |{(x, y)|x, y \in G, xy = yx}|/|G|^2. In this paper, we first extend this concept of finite groups to the commutativity degree of fuzzy subgroups. Then, by using the numerical solutions of the equation xy − zu \eqiv t(mod n), we give explicit formulas for the commutativity degree of fuzzy subgroups of 2-generated groups of nilpotency class 2. Finally we show that this method also works for a large class of finite groups, including metabelian groups. | ||
