Frobenius不等式的线性变换式证明 - 知乎 - 知乎专栏

Web所谓Frobenius不等式，是指不等式：设 A,B,C 分别为 m \times n,n \times s,s \times t 矩阵，则：. r(ABC) \geq r(AB)+r(BC) - r(B). 如果取 C 为n阶单位矩阵,那么不等式化为 r(AB) … WebApr 1, 1997 · Abstract. This paper considers the H∞ control problem for descriptor systems that possibly have impulsive modes and/or jω-axis zeros. First, we propose matrix inequalities that give a generalized stability condition and an H∞ norm condition for descriptor systems. Using these matrix inequalities, we show that the solvability of a set … ffw st martin am grimming

矩阵的 Frobenius norm (Frobenius 范数) - 简书

WebAll we need is the following well known identity (see this answer for a proof): (1) ρ ( A B) = ρ ( B) − dim ( im ( B) ∩ ker ( A)) and the following observation: (2) im ( B C) ∩ ker ( A) ⊆ im ( B) ∩ ker ( A) which holds since im ( B C) ⊆ im ( B). Now we want to write ρ ( A B C) in such a way that im ( B C) ∩ ker ( A) pops up, so ...
