| Abstract: | A graph is point determining if distinct points have distinct neighborhoods. In this paper we investigate the nucleus G0={υ?G:G–υ is point determining} of a point determining graph G. In particular, we characterize those graphs that are the nucleus of some connected point determining graph. |
