| Abstract: | According to the extensive theory of topological degree for set-valued mapping ,the authors derive the topological degree for upper semicontinuous set-valued 1-set-contractive mapping. With the topological degree, the fixed theorems for upper semicontinuous set-valued 1-set-contractive mapping is studied. |
