    "abstract": "The equivalence of the discrete isotropic Heisenberg magnet (IHM) model and\nthe discrete nonlinear Schr\\\"odinger equation (NLSE) given by Ablowitz and\nLadik is shown. This is used to derive the equivalence of their discretization\nwith the one by Izergin and Korepin. Moreover a doubly discrete IHM is\npresented that is equivalent to Ablowitz\u0027 and Ladiks doubly discrete NLSE.",
