Integral Majorization Theorem for Invex Functions [PDF]
Abstract and Applied Analysis, 2014 We obtain some general inequalities and establish integral inequalities of the majorization type for invex functions. We give applications to relative invex functions.

A class of generalized invex functions and vector variational-like inequalities [PDF]
Journal of Inequalities and Applications, 2017 In this paper, a class of generalized invex functions, called ( α , ρ , η ) $(\alpha,\rho,\eta)$ -invex functions, is introduced, and some examples are presented to illustrate their existence.

Invex functions and duality [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1985 AbstractFor both differentiable and nondifferentiable functions defined in abstract spaces we characterize the generalized convex property, here called cone-invexity, in terms of Lagrange multipliers. Several classes of such functions are given.

Multiobjective fractional programming problems and the sufficient condition involving Hb – (p, r)-η- invex function [PDF]
MATEC Web of Conferences, 2021 On the basis of arcwise connected convex functions and (p, r) −η - invex functions, we established Hb –(p, r) –η- invex functions. Based on the generalized invex assumption of new functions, the solutions of a class of multiobjective fractional ...

Optimality Conditions for Preinvex Functions Using Symmetric Derivative [PDF]
Operations Research and Decisions, 2022 As a generalization of convex functions and derivatives, in this paper, the authors study the concept of a symmetric derivative for preinvex functions. Using symmetrical differentiation, they discuss an important characterization for preinvex functions ...

E-invexity and generalized E-invexity in E-differentiable multiobjective programming [PDF]
ITM Web of Conferences, 2019 In this paper, a new concept of generalized convexity is introduced for not necessarily differentiable vector optimization problems. For an E-differentiable function, the concept of E-invexity is introduced as a generalization of the E-differentiable E ...

Higher order duality in multiobjective fractional programming problem with generalized convexity [PDF]
Yugoslav Journal of Operations Research, 2017 We have introduced higher order generalized hybrid B -(b,ρ,θ,˜ρ,˜r)-invex function. Then, we have estabilished higher order weak, strong and strict converse duality theorems for a multiobjective fractional programming problem with support ...
