The Property of The Concave Function and Application
Abstract:Concave function is a kind of important function. Because we can solve some complicated questions better and concisely by using its property.The paper focuses on concave function’s property. It will introduce the definition and properties of concave function and weakly logarithmically concave function.Then we can take advantage of their properties to explore function’s basic features,such as its maximum or minimum number, monotonic, concave-convex, continuity unequal etc.The paper will present some specific examples to validate the application of these properties at the same time.
