摘要

本文研究了Eaton三元组$ (V,G,D) $上的一个von neumann型不等式，其中$ V $是一个实内积空间，$ G $是正交组$ O (V) $的紧子群，$ D \子集V $是一个闭凸锥。利用Eaton三元组的内部结构，给出了这个不等式的一个改进。在特殊情况$ G = O (V) $下，得到了Cauchy-Schwarz不等式的一个改进。

Refinement of von Neumann-type inequalities on product Eaton triples

In this paper, a von Neumann-type inequality is studied on an Eaton triple $ (V,G,D) $, where $ V $ is a real inner product space, $ G $ is a compact subgroup of the orthogonal group $ O (V) $, and $ D \subset V $ is a closed convex cone. By using an inner structure of an Eaton triple, a refinement of this inequality is shown. In the special case $ G = O ( V ) $, a refinement of the Cauchy-Schwarz inequality is obtained.
