"Webtheta functions are simply 𝜃shifted by the half-periods of 𝛬, modulo a certain scaling factor. This is explained in the more general theory of theta functions with characteristic, which is unfortunately beyond the scope of this essay. The Jacobi theta functions are also quasi-elliptic with respect to the same lattice 𝛬. " - Theta functions igusa
