In this paper, we introduce a new concept of sets and a new class of functions called E-
univex sets and E-univex functions, respectively. For an E-differentiable function, the …

In this paper, a class of E-differentiable multiobjective programming with multiple objective
functions and with both inequality and equality constraints is considered. The so-called E …

In this paper, a new concept of generalized convexity is introduced for not necessarily
differentiable multiobjective programming problems with $ E $-differentiable functions …

In this paper, a new class of generalized convex optimization problems with a multiple
interval-valued objective function is considered. The concepts of B-preinvexity, B-invexity …

In this paper, we study the notion of strong invexity with respect to the E-operator. We
discuss the necessary and sufficient conditions for the considered E-minimax fractional …

In this paper, a new concept of generalized convexity is introduced for not necessarily
differentiable vector optimization problems with E-differentiable functions. Namely, for an E …

In this paper, we introduce a new concept of sets and a new class of functions called α-E-
invex sets and VE-preinvex functions. Furthermore, a new concept of generalized convexity …

In this paper, a new concept of generalized convexity is introduced for (not necessarily)
differentiable optimization problem with E-differentiable functions. Namely, for an E …

In this article, we deal with nonconvex fractional programming problems involving E-
differentiable functions (FPE). The so-called E-Karush-Kuhn-Tucker sufficient E-optimality …

In this paper, the class of E-differentiable vector optimization problems with both inequality
and equality constraints is considered. For such (not necessarily) differentiable vector …
