چکیده
|
Let r be the set of real numbers and (y, ii.ii) be a real quasi-β-banach space. in this paper, we prove the hyers-ulam stability on a restricted domain in quasi-β-spaces for the following two radical functional equations f (√x² + y²) = f(x) + f(y) and f (√x² + y²) = g(x) + f(y) where f, g : r → y. also, we discuss an asymptotic behavior for these equations.
