CORRIGENDUM: Spectra and pseudo-spectra of tridiagonal k -Toeplitz matrices and the topological origin of the non-Hermitian skin effect (2025 J. Phys. A: Math. Theor. 58 205201)
Abstract
Abstract An error in Ammari et al (2025 J. Phys. A: Math. Theor. 58 205201; theorem 3.3) is pointed out. Due to this, some results have to be corrected. However, the main results, namely the spectrum of the k -Toeplitz operator and the results regarding the exponential decay of eigenvectors, still hold.
