Strongly E-convex sets and strongly E-convex functions
Ebrahim A. Youness, Tarek Emam · Journal of Interdisciplinary Mathematics · 2005
A class of E-convex sets and a class of E-convex functions are extended to the so called strongly E-convex sets and strongly E-convex functions. In this extension we take into account the images of two points x and y under an E : Rn → Rn operator besides the two points themselves.
