Abstract. Let G be a finite group and let C = {(x, y) ∈ G × G ∣ xy = yx}. Then Pr(G) = ∣C∣/∣G∣ is the probability that two elements of G, chosen randomly with replacement, commute. This probability is a well known quantity, called commutativity degree of G, and indeed gives us an estimation of commutativity in G. In the last four decades this subject has enjoyed a flourishing development. In this article, we give a brief survey on the development of this subject and then we collect several of…
