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 ...

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 ...

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 Wolfe Type Symmetric Fractional Programming Problem Under Generalized Assumptions [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2022 The Wolfe-type model over arbitrary cones is a new sort of model that we introduce in this article. We defend duality theorems under more generalized higher-order assumptions in the section after this.

Bulletin of Latin American Research, Volume 42, Issue 5, Page 707-720, November 2023., 2023 Based on analysis of Brazilian‐Spanish cooperation in Latin America, this article aims to contribute to the discussion on whether South–South Cooperation (SSC) represents an alternative model with specific and differentiated objectives, or if it largely reproduces the constraints and interests traditionally associated with the North–South model, but ...

Sufficient optimality criteria and duality for multiobjective variational control problems with B-(p,r)-invex functions [PDF]
Opuscula Mathematica, 2014 In this paper, we generalize the notion of \(B\)-\((p,r)\)-invexity introduced by Antczak in [A class of \(B\)-\((p; r)\)-invex functions and mathematical programming, J. Math. Anal. Appl. 286 (2003), 187-206] for scalar optimization problems to the case

Asymptomatic idiopathic intracranial hypertension: Prevalence and prognosis
Clinical &Experimental Ophthalmology, Volume 51, Issue 6, Page 598-606, August 2023., 2023 Abstract Background Little is known about the presentation and prognosis of asymptomatic idiopathic intracranial hypertension (IIH). Papilloedema can be found incidentally on routine fundus examination, with many of these patients actually having symptoms on direct questioning. The aim was to evaluate visual and headache outcomes in people with IIH who

Criterion for Generalized Weakly Fuzzy Invex Monotonocities
Advances in Fuzzy Systems, 2018 The present paper deals with the concepts of generalized fuzzy invex monotonocities and generalized weakly fuzzy invex functions. Some necessary conditions for weakly fuzzy invex monotonocities are presented.

Optimality conditions and duality in multiobjective programming with invexity [PDF]
Yugoslav Journal of Operations Research, 2008 (', ρ)-invexity has recently been introduced with the intent of generalizing invex functions in mathematical programming. Using such conditions we obtain new sufficiency results for optimality in multiobjective programming and extend some classical ...
