Abstract
It is well known that the sum of two linear continuous narrow operators in the spaces Lp with 1 p ∞ is not necessarily a narrow operator However the sum of a narrow operator and a compact linear continuous operator is a narrow operator In a recent paper Pliev and Popov originated the investigation of nonlinear narrow operators and in particular of orthogonally additive operators As our main result we prove that the sum of a narrow orthogonally additive operator and a finiterank laterallytonorm continuous orthogonally additive operator acting from an atomless Dedekind complete vector lattice into a Banach space is a narrow operator
