| Title: | Retractions from C(X) onto X and continua of type N |
| Authors: | Capulin, F
Charatonik, WJ |
| Issue Date: | 2007 |
| Abstract: | We show that if a metric continuum X is of type N, then there is no a retraction from the hyperspace of subcontinua C(X) onto X, and X admits no mean. We also give an example which answers a question posed by T. J. Lee related to this topic. |
