Abstract
We study the Hyers-Ulam stability theory of a four-variate
Jensen-type functional equation by considering the approximate
remainder ϕ and obtain the corresponding error formulas. We
bring to light the close relation between the β-homogeneity
of the norm on F∗-spaces and the approximate remainder ϕ,
where we allow p,q,r, and s to be different in their
Hyers-Ulam-Rassias stability.
