Several new kinds of generalized E-preinvexity and generalized invariant E-monotonicity are introduced in the setting of Banach spaces. The relations between E-preinvexity, E-prequasiinvexity, (pseudo, quasi) E-invexity and invariant (pseudo, quasi) E-monotonicity are studied, which can be viewed as an extension of some known results. 相似文献
