| Abstract: | In this paper, we prove that if a perfect GO-space  has a  -discrete dense set, then  has a perfect linearly ordered extension. This answers a problem raised by H. R. Bennett, D. J. Lutzer and S. Purisch. And the result is also a partial answer to an old problem posed by H. R. Bennett and D. J. Lutzer. |
| Keywords: | $sigma$-discrete set perfect LOTS GO-space extension |
