On algebra homomorphisms in complex almost $f$ -algebras

Similarity:

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.

Similarity:

Let $A$ be a uniformly complete almost $f$ -algebra and a natural number $p \in {3, 4, \dots}$ . Then $Π_{p} (A) = {a_{1} \dots a_{p}; a_{k} \in A, k = 1, \dots, p}$ is a uniformly complete semiprime $f$ -algebra under the ordering and multiplication inherited from $A$ with $Σ_{p} (A) = {a^{p}; 0 \leq a \in A}$ as positive cone.
