Some properties of semi-EE-preinvex maps in Banach spaces

In this paper, we extend the class of EE-convex, semi-EE-convex, EE-preinvex functions in nn-dimensional spaces introduced by Youness (1999) [10], respectively by Syau and Lee (2005) [14], Chen (2002) [12], Fulga and Preda (2009) [15] to semi-EE-preinvex maps in Banach spaces. Some properties of these classes are studied.
