Almost disjointness preservers (1508.04074v1)
Published 17 Aug 2015 in math.FA
Abstract: We study the stability of disjointness preservers on Banach lattices. In many cases, we prove that an "almost disjointness preserving" operator is well approximable by a disjointess preserving one. However, this approximation is not always possible, as our examples show.
