Abstract: Asymptotic behavior of the integral

*w*is a large positive parameter. It is shown that decays exponentially like , , when is an entire function subject to a suitable growth condition. A complete asymptotic expansion is obtained when is a meromorphic function satisfying the same growth condition. Similar results are given when has some specific branch point singularities.
