dc.description.abstract | Several new undecidability results on isomorphism problems for automatic structures are shown: (i) The isomorphism problem for automatic equivalence relations is \Pi^0_1-complete, (ii) The isomorphism problem for automatic trees of height n≥2 is \Pi^0_{2n-3}-complete, (iii) The isomorphism problem for automatic linear orders is not arithmetical. | |
