Webcolored graph G with ∆(G) = 4 is proper disconnected. Then we give the proper disconnection numbers of graphs with ∆(G) ≤ 3, and propose a question. We first give some notations. For an edged-colored graph G, let F be a proper edge-cut of G. If F is a matching, then F is called a matching cut. Furthermore, if F is an x-y proper edge-cut ... Weba connected graph G,theproper disconnection number of G, denoted by pd(G),is defined as the minimum number of colors that are needed in order to make G proper disconnected. A proper disconnection coloring with pd(G) colors is called an pd-coloring of G. Clearly, for any pair of vertices of a graph, a rainbow cut is definitely a proper edge-cut.
