Bessel function asymptotics: a relation due to Lommel

Classical Analysis and ODEs 2018-08-06 v1 Complex Variables

Abstract

We show that the Bessel function asymptotic relation Jν2(z)+Jν+12(z)2/(πz)J_{\nu}^2(z) + J_{\nu + 1}^2 (z) \sim 2/(\pi z) of Lommel is valid when zz is real but can fail otherwise.
