Complex Variables 2024-08-13 v1

Abstract

We establish a version of the Landen's transformation for Weierstrass functions and invariants that is applicable to general lattices in complex plane. Using it we present an effective method for computing Weierstrass functions, their periods, and elliptic integral in Weierstrass form given Weierstrass invariants g2g_2 and g3g_3 of an elliptic curve. Similarly to the classical Landen's method our algorithm has quadratic rate of convergence.
