Abstract:
In this paper, we study a new class of locally dominated orthogonally additive operators on lattice-normed spaces (LNS). In the first part of the paper, sufficient conditions for the existence of a local exact majorant of a locally dominated operator and formulas for its calculation are given. The second part shows that the $C$-compactness of a dominated orthogonally additive operator acting from a decomposable lattice-normed space to a Banach space with mixed norm implies the $C$-compactness of its exact majorant.
Keywords:
orthogonally additive operator, $x$-locally dominated operator, $x$-local exact majorant, positive operator, $C$-compact operator, lattice-normed space, vector lattice, Banach lattice.
