Bessel function asymptotics: a relation due to Lommel

P. L. Robinson

We show that the Bessel function asymptotic relation $J_{ν}^{2} (z) + J_{ν + 1}^{2} (z) \sim 2/ (π z)$ of Lommel is valid when $z$ is real but can fail otherwise.

Julia operators and Halmos dilations

P. L. Robinson

We offer a simple direct proof of the unitarity of the Julia operator associated to a contraction $A$ , from which follow the intertwining identity $(I - A A^*)^{1/2} A = A (I - A^*…
