摘要

我们给出了积和式与半积和式的新上界,其对复矩阵尤为有用。多维积和式与超半积和式也一并被考虑。这些积和式界改进了 Carlen、Lieb 与 Loss(2006, Methods and Applications of Analysis 13, 1--17)以及 Cobos、K"uhn 与 Peetre(2006, Integral Equations and Operator Theory 56, 57--70)的 Hadamard 型不等式。我们的证明基于一个更一般的不等式,其可应用于所讨论矩阵函数的广义 Laplace 型展开。作为应用,我们给出了随机对角和特征函数的新界。数值比较显示了我们某些积和式界的性能。
