Abstract: The notion of s-quasiconvex function is presented from the paper “Stable Generalization of convex functions” by H.X.Phu and P. T. An. These functions are quasiconvex, expilicitly quasiconvex, and pseudoconvex if they are continuously differentiable. Especially, the s-quasiconvexity is stable with repect to the following important properties (P1) all power level sets are convex, (P2) each local minimum is global minimum is a global minimum, and (P3) each stationary point is a global minimizer. |
