On some generalizations of convex sets and convex functions
(1985) In L'analyse numérique et la théorie de l'approximation 14(1). p.1-6- Abstract
- A set $C$ in a topological vector space is said to be weakly convex if for any $x,y$ in $C$ there exists $p$ in $(0,1)$ such that $(1-p)x+py\in C$. If the same holds with $p$ independent of $x,y$, then $C$ is said to be $p$-convex. Some basic results are established for such sets, for instance: any weakly convex closed set is convex.
