Some results on mathematical programming with generalized ratio invexity. (English) Zbl 0946.90089

Summary: A generalized ratio invexity concept has been applied for single objective fractional programming problems. A concept which has been invoked seems to be more general than the one used earlier by Khan and Hanson in such contexts. Further, duality results for fractional programs have also been obtained.
