Integral representations for elliptic functions

We derive new integral representations for constituents of the classical theory of elliptic functions: the Eisenstein series, andWeierstrass’ ℘ and ζ functions. The derivations proceed from the Laplace– Mellin representation of multipoles, and an elementary lemma on the summation of 2D geometric series. In addition, we present results concerning the analytic continuation of the Eisenstein series to an entire function in the complex plane, and the value of the conditionally convergent series, denoted by E2 below, as a function of summation over increasingly large rectangles with arbitrary fixed aspect ratio.1 Published by Elsevier Inc.
