摘要
Sn(R)记实数域R上全体n(n≥2)阶对称矩阵构成的线性空间,Hn(C)记复数域R上全体n阶Hermitian矩阵构成的线性空间.确定了从Sn(R)到Hn(C)保秩1的加法映射的结构.
Let Sn (R) be the space of n x n (n≥2) symmetric matrices over the real number field, and let Hn (C) be the space of n×n Hermitian matrices over the complex number field C. Struction of additive maps preserving rank - 1 matrices from Sn (C) to Hn (C) are characterized.
