Abstract
In this paper, the Schwarz type and Schwarz-Pick type inequalities for solutions of α-harmonic equation () are investigated. By making use of the integral of trigonometric functions, we obtain these two types of inequalities in terms of hypergeometric functions which improve the corresponding results due to Khalfallah et al. (Complex Var. Elliptic Equ., 2023) and Li et al. (Bull. Malays. Math. Sci. Soc., 2022).
本文研究了α-调和方程(α>−1)解的Schwarz型不等式和Schwarz- pick型不等式。利用三角函数的积分,得到了这两类关于超几何函数的不等式,改进了Khalfallah等(Complex Var. Elliptic equation)的相应结果。Li et al. (Bull., 2023)。马来人。数学。科学。Soc。, 2022)。
