We show that every bijection Ψ between complex ∗-algebras satisfying Ψ(A*B−ξBA)=Ψ(A)*Ψ(B)−ξΨ(B)Ψ(A), for a fixed ξ≠0, is additive as soon as its domain is a prime unital ∗-algebra with a nontrivial projection, with nothing assumed about its codomain at all. In the additivity theorems for products built from the involut...
This study aims to develop a nonlinear SVLIQR epidemic model to investigate measles transmission dynamics by incorporating vaccination, latency, quarantine, and treatment effects. The qualitative properties of the model, including positivity and boundedness of solutions, are established. The basic reproduction number i...

In this paper we prove a transfer principle for Banach algebras and use it to show that, for local identities of product type, the algebraic hypotheses of the commutativity theorems of Yood type are superfluous. Such theorems assume an algebraic identity only on a small part of the algebra and only with an exponent tha...
