 Optimality conditions and duality for semi-infinite programming involving semilocally type I-preinvex and related functions Commun. Korean Math. Soc. 2012 Vol. 27, No. 2, 411-423 https://doi.org/10.4134/CKMS.2012.27.2.411Printed June 1, 2012 Monika Jaiswal, Shashi Kant Mishra, and Bader Al Shamary Banaras Hindu University, Banaras Hindu University, Kuwait University Abstract : A nondifferentiable nonlinear semi-infinite programming problem is considered, where the functions involved are $\eta$-semidifferentiable type I-preinvex and related functions. Necessary and sufficient optimality conditions are obtained for a nondifferentiable nonlinear semi-infinite programming problem. Also, a Mond-Weir type dual and a general Mond-Weir type dual are formulated for the nondifferentiable semi-infinite programming problem and usual duality results are proved using the concepts of generalized semilocally type I-preinvex and related functions. Keywords : multiobjective programming, semi-infinite programming, optimality, duality MSC numbers : 90C29, 90C34, 90C46 Downloads: Full-text PDF
