This is a study of morphisms in the category of finite dimensional absolute valued algebras, whose codomains have dimension four. We begin by citing and transferring a classification of an equivalent category. Thereafter, we give a complete description of morphisms from one-dimensional algebras, partly via solutions of real polynomials, and a complete, explicit description of morphisms from two...

This paper deals with a property which is equivalent to generalised-lushness for separable spaces. It thus may be seemed as geometrical of Banach space ensures the have Mazur–Ulam property. We prove that X enjoys this if and only C(K, X) also show same result holds $$L_\infty (\mu ,X)$$ $$L_1(\mu .
