摘要:
在正定算子的设定下,我们研究了拟算术平均(Hölder平均)、Rényi幂平均这类幂平均的近序性质。我们得到了谱几何平均与Wasserstein平均关于近序的参数单调性,以及二者之间的近序关系。此外,我们还确立了拟算术平均关于近序的参数单调性,以及Rényi幂平均按近序收敛于log-Euclidean平均的结论。
英文摘要:
On the setting of positive definite operators we study the near-order properties of power means such as the quasi-arithmetic mean (Hölder mean) and Rényi power mean. We see the monotonicity of spectral geometric mean and Wasserstein mean on parameters with respect to the near-order and the near-order relationship between the spectral geometric mean and Wasserstein mean. Furthermore, the monotonicity of quasi-arithmetic mean on parameters and the convergence of Rényi power mean to the log-Euclidean mean with respect to the near-order have been established.
