Abstract

Let rk(n)r_{k}(n) denote the number of representations of the positive integer nn as the sum of kk squares. We prove a new summation formula involving rk(n)r_{k}(n) and the Bessel functions of the first kind, which constitutes an analogue of a result due to the Russian mathematician A. I. Popov.
