Abstract:
We consider the extension of an orthogonally additive operator from a lateral ideal and a lateral band to the whole space. We prove in particular that every orthogonally additive operator, extended from a lateral band of an order complete vector lattice, preserves lateral continuity, narrowness, compactness, and disjointness preservation. These results involve the strengthening of a recent theorem about narrow orthogonally additive operators in vector lattices.
Keywords:
vector lattice, abstract Urysohn operator, lateral ideal, lateral band, smallest extension, laterally continuous operator, narrow operator.
