Algebras of Lebesgue and KB regular operators in Banach lattices
Abstract
It is shown that the regularly Lebesgue and regularly (quasi) KB operators in a Banach lattice E form operator algebras and, for Dedekind complete E, even Banach lattice algebras. We also prove that a Banach lattice E with order continuous norm is a KB-space iff each positive compact operator in E is a KB operator.
