| Abstract: | Studied in this paper are the respective necessary and sufficient conditions, for point v of graph G being in a negative point (C(v)<0), a zero point (C(v) =0), and a positive point. |
| Keywords: | cohesiveness neighbour sct of a subset of point left right neigh- bour set single neighbour point k-single neighbour point excluded negative point excluded zero point |
