On algebra homomorphisms in complex almost \(f\)-algebras. (English) Zbl 1070.06008
Summary: Extensions of order-bounded linear operators on an Archimedean vector lattice to its relatively uniform completion are considered and are applied to show that the multiplication in an Archimedean lattice-ordered algebra can be extended, in a unique way, to its relatively uniform completion. This is applied to show, among other things, that any order-bounded algebra homomorphism on a complex Archimedean almost \(f\)-algebra is a lattice homomorphism.
