摘 要:
证明了矩阵A的两个矩阵多项式秩的和等于它们最大公因式与最小公倍式秩的和。其结果不仅概括了已有文献的相关结论,而且作为应用解决了关于矩阵的一次多项式秩的恒等式的两个猜想。[著者文摘]

Abstract:
The sum of ranks of two matrix polynomials is equal to the sum on ranks of the greatest common divisor and the smallest common multiple of matrices. It not only induces the corresponding results in the present literatures but also solves two conjectures on rank identities of order one polynomial as an application.[著者文摘]
