摘要
定义了两个新的双曲函数及反双曲函数的复合平均,运用分析方法,研究了这两个平均的Schur幂凸性,给出了判定的充要条件.
The complex average of two hyperbolic function and inverse hyperbolic function is defined. The Schur power convexity of those two mean is studied by using the analytical method.The necessary and sufficient conditions for the judgment are given.
