Perturbation of invariant subspaces for ill-conditioned eigensystem

He Lyu, Rongrong Wang

Given a diagonalizable matrix $A$ , we study the stability of its invariant subspaces when its matrix of eigenvectors is ill-conditioned. Let $X_{1}$ be some invariant subsp…

On the $ℓ^{\infty}$ -norms of the Singular Vectors of Arbitrary Powers of a Difference Matrix with Applications to Sigma-Delta Quantization

Theodore Faust, Mark Iwen, Rayan Saab +1

Let $∥ A ∥_{m a x} := max_{i, j} ∣ A_{i, j} ∣$ denote the maximum magnitude of entries of a given matrix $A$ . In this paper we show that $$\max \left\{ \|U_r \|_{\max},\|V_r\|_{\max}…
