On ratio invexity in mathematical programming. (English) Zbl 0872.90094

Summary: The nonlinear fractional programming problem is considered. The functions involved in the objective function and constraints are assumed to be invex and differentiable. It is shown that the ratio of invex functions is invex. Sufficient optimality and duality theorems are presented for an invex fractional programming problem.
