这完成了证明. 2.2 Bauer-Fike 定理 如果 μ 是 A + E ∈ C n × n 的特征值且 X 1 A X = D = diag (λ 1, ⋯, λ n),则 min λ ∈ λ (A) | λ μ | ≤ κ p (X) ‖ E ‖ p, 1 ≤ p ≤ + ∞. 证明 如果 μ ∈ λ (A),则定理显然是正确的。 不失一般性,假设 μ ∉ λ (A)。

Sep 29, 2024 · 定理 其特征值排列次序为 λ1≥λ2≥...≥λn ,则 ,λ1=maxx∈Rn,x≠0R (x),λn=minx∈Rn,x≠0R (x) 【因此Rayleigh商的最大最小值分别对应着特征值的最大最小值】 三、 扰动 对矩阵特征值的影响 定理 Bauer-Fike定理:设 n 阶方阵 A 可对角化,矩阵 P 使得 P−1AP=diag (λ1,λ2,...λn)
在其物质中,它指出了一个绝对的上限,用于将一个扰动的矩阵特征值偏离确切矩阵的正确选择的特征值。 从非正式的角度来看,它说的是 特征值的敏感性是由特征向量矩阵的条件数估算的。 该定理在1960年由 Friedrich L. Bauer 和CT Fike证明。
