Research output: Contribution to journalArticlepeer-review


Let a(n) be an arithmetical function, and consider the Riesz sum Ar(x) = Sn£xa(n)(x-n)r. For a(n) belonging to a certain class of arithmetical functions, Ar(x) can be expressed in terms of an infinite series of Bessel functions. K. Chandrasekharan and R. Narasimhan have established this identity for the widest known range of r. Their proof depends upon equi-convergence theory of trigonometric series. An alternate proof is given here which uses only the classical theory of Bessel functions.
