摘要: Abstract In this paper we introduce a new type of generalized invex function, called (p, r) − ρ − (η, θ)-invex function and study symmetric duality results under these assumptions. our the nonnegative orthants for constraints are replaced by closed convex cones their polars. We establish weak strong theorems (p, r) − ρ − (η, θ)-invexity assumptions dual problems. also give many examples to justify results.
