Almost \(f\)-algebras: Commutativity and the Cauchy-Schwarz inequality
The authors give a short and direct proof of the Scheffold-Basky-Triki theorem claiming that every almost \(f\)-algebra is commutative. Also given is an abstraction of the Cauchy-Schwartz inequality for almost \(f\)-algebra-valued bilinear mappings.
