Invex functions and constrained local minima [PDF]
If a certain weakening of convexity holds for the objective and all constraint functions in a nonconvex constrained minimization problem, Hanson showed that the Kuhn-Tucker necessary conditions are sufficient for a minimum. This property is now generalized to a property, called K-invex, of a vector function in relation to a convex cone K.

INFINITELY MANY INVEX FUNCTIONS WITHOUT CONVEXITY [PDF]
The paper under review provides several examples of smooth and nonsmooth invex functions that are not necessarily convex. However, as the authors themselves mention, invexity has not yet found a significant application in mathematical optimization (or in any other field).

Further Study on Strong Lagrangian Duality Property for Invex Programs via Penalty Functions [PDF]
We apply the quadratic penalization technique to derive strong Lagrangian duality property for an inequality constrained invex program. Our results extend and improve the corresponding results in the literature.

Invexity of supremum and infimum functions [PDF]
Under suitable assumptions we establish the formulas for calculating generalised gradients and generalised directional derivatives in the Clarke sense of the supremum and the infimum of an infinite family of Lipschitz functions. From these results we derive the results ensuring such a supremum or infimum are an invex function when all functions of the ...

Quantum ostrowski type inequalities for pre-invex functions
Abstract In this paper, using the quantum derivatives and quantum integrals, we prove some new quantum Ostrowski’s type inequalities for pre-invex functions. Furthermore, in the special cases of newly developed inequalities, we obtain different new and existing Ostrowski’s type inequalities.

Semi-invex functions and their subdifferentials [PDF]
We introduce the notion of semi-invex function (non-smooth) and the associated subdifferential. We study their properties and establish the conditions for optimality in constrained and unconstrained minimisation problems.

Minimax fractional programming involving generalised invex functions [PDF]
AbstractThe convexity assumptions for a minimax fractional programming problem of variational type are relaxed to those of a generalised invexity situation. Sufficient optimality conditions are established under some specific assumptions. Employing the existence of a solution for the minimax variational fractional problem, three dual models, the Wolfe ...

Generalized Differentiable -Invex Functions and Their Applications in Optimization [PDF]
The concept of -convex function and its generalizations is studied with differentiability assumption. Generalized differentiable -convexity and generalized differentiable -invexity are used to derive the existence of optimal solution of a general optimization problem.

Optimality and Duality of Semi-Preinvariant Convex Multi-Objective Programming Involving Generalized (F,α,ρ,d)-I-Type Invex Functions [PDF]
Multiobjective programming refers to a mathematical problem that requires the simultaneous optimization of multiple independent yet interrelated objective functions when solving a problem.
