| Abstract: | First, the continuity and boundedness of convex functions are discussed and the concept of extended monotone is defined. Based on this, the extended monotonicity of convex functions both in open intervals and closed intervals is discussed. A method to judge the convexity and monotonicity of the integral of order n is derived by applying the extended monotonicity to integrable functions. |
