| Abstract: | For a connected graph G with girth of least five, it is proved in this paper that if, for each vertex v of G, the independence numbor of the subgraph reduced by the venices that are of distance two or three from v is not greater than two times the minimum degree minus three, then G has a dominating cycle. |

| Keywords: | dominating cycle local condition minimum degree independence number |
