title = {{The Generators of all Polynomial Relations among Jacobi Theta Functions}},

language = {english},

abstract = {In this article, we consider the classical Jacobi theta functions
$\theta_i(z)$, $i=1,2,3,4$ and show that the ideal of all polynomial
relations among them with coefficients in
$K :=\setQ(\theta_2(0|\tau),\theta_3(0|\tau),\theta_4(0|\tau))$ is
generated by just two polynomials, that correspond to well known
identities among Jacobi theta functions.
