摘要
通过线性空间的线性变换讨论了Sylvester与Frobenius不等式取等号的条件,并将它们推广到矩阵多项式中,建立了一类广泛的秩恒等式.
By using the linear transformation of linear space, this paper discusses the conditions by which the equal signs come into existence in Sylvester and Frobenius inequalities. Subsequently, the conditions are extended to the matrix polynomial, and a kind of universal rank identities is constructed.
