We hereby generalize previous results into several directions: We generalize the subsequence theorem from dimension N = 1 (see Rabinovich, Roch and Silbermann (2008) [18]) to arbitrary dimensions N ≥ 1; and even for the case of the full sequence, our result is new in dimensions N > 2 and it corrects a mistake in the literature for N = 2. Moreover, we allow the truncations to be taken by homothetic copies of very general starlike geometries Ω ∈ RN rather than convex polytopes. © 2009 IMACS.en0168-9274Applied numerical mathematics20104501512Band-dominated operatorFinite section methodProjection methodsStabilityMathematikThe finite section method and stable subsequencesJournal Article10.1016/j.apnum.2009.11.006Other
