Set-valued \(\alpha\)-almost convex mappings
\textit{J. García-Falset}, \textit{E. Llorens-Fuster} and \textit{B. Sims} [Nonlinear Anal. Theory, Methods Appl. 32, No. 5, 601-608 (1998)] defined a class of (single-valued) mappings called \(\alpha\)-almost convex mappings. The author of this paper extends this definition to the case of set-valued mappings. The purpose of this attempt is to prove some new theorems of fixed points for such mappings. It is an interesting work.
