星像函数和关于K折对称点近于凸函数的一些充分条件

摘要: 文先建立了一个微分不等式, 然后利用这一微分不等式我们得到一些新的星像函数和关于k折对称点近于凸函数的充分条件, 也推广了一些作者的结果.

Abstract: In this paper, we first establish a differential inequality. Next by using this differential inequality, we obtain some new sufficient conditions for starlike functions and close-to-convex functions with respect to k-symmetric points, which generalize some results of some authors.
