Ravi P. Agarwal, Izhar Ahmad, Akhlad Iqbal, Shahid Ali · Optimization · 2011
In this article, we introduce semistrictly geodesic η-preinvex functions on Riemannian manifolds, geodesic G-invex sets and study their properties. Our results extend and improve the results of Yang and Li [X. Yang and D. Li, Semistrictly preinvex functions, J. Math. Anal. Appl. 258 (2001), pp. 287–308]. Example is constructed in support of our defnition.
