• Mar 24, 2026 Spectra And Pseudospectra The Behavior Of ctrum differ from the spectrum for nonnormal operators? The pseudospectrum includes not only points in the spectrum but also those complex numbers where the resolvent norm is large, reflecting sensitivity to perturbations. For nonnormal operators, pseudospectra provide a more detailed picture of o By Demond Larson
• Aug 19, 2025 spectra and pseudospectra the behavior of nonnorma iny perturbation might cause the eigenvalues to shift dramatically or even cause the matrix to behave in an entirely different manner. This sensitivity can have profound implications in numerical computations, stability analysis By Don Aufderhar
