2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/38472I comment on the above paper(s) discussing the issue of non-ultralocality for Ginsparg-Wilson fermionic actions. The purpose of this note is to point out that the new claim in "v3" (Feb 24, 2000), alleging the proof for "all Ginsparg-Wilson fermions", might not be substantiated. The remarkable evolution of versions of this paper is put in context with the literature existing at the time of their appearance.4 pages, LATEXHigh Energy Physics - Latticetext
