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