Our results show that such a sequence (An), no matter how the points of truncation are chosen, is always stable – implying that An is invertible for sufficiently large n and A–1n → A–1 pointwise.enFibonacci HamiltonianFinite section methodJacobi operatorLimit operatorsBook Part10.1007/978-3-319-75996-8_20Other
