On Multivalued Nonexpansive Mappings in ℝ‐Trees
Khanitin Samanmit, Bancha Panyanak · Journal of Applied Mathematics · 2012
The relationships between nonexpansive, weakly nonexpansive, *‐nonexpansive, proximally nonexpansive, proximally continuous, almost lower semicontinuous, and ɛ‐semicontinuous mappings in ℝ‐trees are studied. Convergence theorems for the Ishikawa iteration processes are also discussed.
