Fischer inequality

WebAug 1, 2024 · If we partition the matrix A into the form A = [A 11 A 12 A 21 A 22] such that the diagonal blocks are square, then Fischer's inequality actually says det ⁡ A ≤ (det ⁡ A 11) (det ⁡ A 22), which, by a simple induction, implies Hadamard's inequality.

Eigenvalue Inequalities for Hermitian Matrices – Nick Higham

WebOne of the exercises my teacher proposed is essentially to prove Weyl's theorem and he suggested using Courant-Fischer. Here's the exercise: suppose A, E ∈ C n × n are hermitian with eigenvalues λ 1 ≥ ⋯ ≥ λ n, ϵ 1 ≥ ⋯ ≥ ϵ n respectively, and B = A + E has eigenvalues μ 1 ≥ ⋯ ≥ μ n. Prove that λ i + ϵ 1 ≥ μ i ≥ ...
