An Exact Integral-to-Sum Relation for Products of Bessel Functions [CL]

http://arxiv.org/abs/2104.10169


A useful identity relating the infinite sum of two Bessel functions to their infinite integral was discovered in Dominici et al. (2012). Here, we extend this result to products of $N$ Bessel functions, and show it can be straightforwardly proven using the Abel-Plana theorem. For $N=2$, the proof is much simpler than that of the former work, and significantly enlarges the range of validity.
