Mond-Weir duality under ρ -(η, θ) -invexity in Banach space

Abstract

The weak, the strong and the converse duality theorems of a pair of nonlinear programming problems are established under ρ -(η, θ) -invexity, generalized ρ -(η, θ) -invexity, strongly ρ -pseudo-invex functions in Banach spaces. The proposed work deals with suitable numerical examples.
