Elliptic Extensions in Statistical and Stochastic Systems - SpringerBriefs in Mathematical Physics 1st ed. 2023 edition

At the elliptic level, many special functions are used, including Jacobi's theta functions, Weierstrass elliptic functions, Jacobi's elliptic functions, and others. Then, the seven systems of orthogonal theta functions, written using a polynomial of the argument multiplied by a single theta function, or pairs of such functions, can be defined.
