    "abstract": "A zero-field Ising model with ferromagnetic coupling constants on the\nso-called Labyrinth tiling is investigated. Alternatively, this can be regarded\nas an Ising model on a square lattice with a quasi-periodic distribution of up\nto eight different coupling constants. The duality transformation on this\ntiling is considered and the self-dual couplings are determined. Furthermore,\nwe analyze the subclass of exactly solvable models in detail parametrizing the\ncoupling constants in terms of four rapidity parameters. For those, the\nself-dual couplings correspond to the critical points which, as expected,\nbelong to the Onsager universality class.",
