Asymptotic behavior of a generalized functional equation

In this paper, we investigate the Hyers-Ulam stability problem of the following functional equation $ f(x+y)+g(x-y) = h(x)+k(y), $ on an unbounded restricted domain, which generalizes some of the results already obtained by other authors (for example [<xref ref-type="bibr" rid=...
