Abstract

Helly’s, Radon’s, and Caratheodory’s theorems are the basic theorems of convex analysis and have an important place. These theorems have been studied by different authors for different classes of convexity. Caratheodory’s theorem for B−1 −convex sets has been proved before by Adilov and Yeşilce. In this article, Helly’s and Radon’s theorems are discussed and examined for these sets.
