Semi-E-Preinvex Functions

open access: yes, 2010
A class of functions called semi--preinvex functions is defined as a generalization of semi--convex functions. Similarly, the concept of semi--quasiconvex functions is also generalized to semi--prequasiinvex functions.

ON STRONGLY GENERALIZED PREINVEX FUNCTIONS

open access: yes, 2005
In this paper, we define and introduce some new concepts of strongly ϕ-preinvex (ϕ-invex) functions and strongly ϕη-monotone operators. We establish some new relationships among various concepts of ϕ-preinvex (ϕ-invex) functions.

Sufficient optimality criteria and duality for multiobjective variational control problems with B-(p,r)-invex functions

open access: yes
Tyt. z nagłówka.Bibliogr. s. 680-681.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.

Invex Nonsmooth Alternative Theorem And Applications

open access: yes, 2015
An invex constrained nonsmooth optimization problem is considered, in which the presence of an abstract constraint set is possibly allowed. Necessary and sufficient conditions of optimality are provided and weak and strong duality results established ...
