    "abstract": "A universal system of difference equations associated with a hyperelliptic\ncurve is derived constituting the discrete analogue of the Dubrovin equations\narising in the theory of finite-gap integration. The parametrisation of the\nsolutions in terms of Abelian functions of Kleinian type (i.e. the higher-genus\nanalogues of the Weierstrass elliptic functions) is discussed as well as the\nconnections with the method of separation of variables.",
