摘要
We give some fixed points theorems for multivalued nonexpansive and pseudocontractive mappings defined on closed convex unbounded subsets of a Banach space. Some of such results extend to the multivoque case a few of the theorems already known for the univoque case, while some other results improve a few of the theorems already known for the multivoque case. © 1991.
