| Abstract: | In the present paper, we establish two fixed point theorems for upper semicontinuous multivalued mappings in hyperconvex metric spaces and apply these to study coincidence point problems and minimax problems. |
| Keywords: | Hyperconvex metric space Metric quasiconvex Metric quasiconcave Lower (upper) semicontinuous multivalued mapping Sub-admissible set |
