Abstract

A square complex matrix A is called (skew) J-Hamiltonian if AJ is (skew) Hermitian where J is a real normal matrix such that J2=−I, where I is the identity matrix. In this paper, we solve the Procr...

正态（偏斜）J-哈密尔顿矩阵和正态J-交映矩阵的逆特征值问题的普罗克鲁斯问题

如果 AJ 是（偏斜）赫米矢矩阵，其中 J 是实正则矩阵，使得 J2=-I，其中 I 是标识矩阵，则一个正方形复矩阵 A 称为（偏斜）J-赫米矢矩阵。在本文中，我们求解了Procr...
