Abstract:In this paper, the concept of generalized increasing-decreasing functions is given, and the relationship between generalized increasing-decreasing and increasing-decreasing functions is discussed. Finally, basing on the generalized gradient, we get a criterion to identify the convexity, generalized pseudoconvexity and quasiconvexity for compound functions.
Keywords:generalized increasing-decreasing functions  compound functions~ generalized convexity
