算子超二次函数的算子Jensen不等式

Operator Jensen's inequality for operator superquadratic functions

M. W. Alomari

摘要:

本文定义了正希尔伯特空间算子的算子超二次函数(算子意义下)。指出了几个例子的一些重要性质以及一些意见,这是有关算子凸性。建立了算子超二次函数Jensen不等式的一个非交换形式的等价表述。本文还将主要结果推广到任何正单位线性映射。

英文摘要:

In this work, an operator superquadratic function (in operator sense) for positive Hilbert space operators is defined. Several examples with some important properties together with some observations which are related to the operator convexity are pointed out. Equivalent statements of a non-commutative version of Jensen's inequality for operator superquadratic function are established. A generalization of the main result to any positive unital linear map is also provided.
