Abstract |
|
Various properties of fixed point sets of monotone singlevalued mappings on dendrites have been studied by L. E. Ward, Jr. and the author. Some of them are extended here to coincidences of two mappings between two trees, and to biconnected multifunctions. Examples are given which show that others are no longer true in these cases. |
