Abstract: We provide requirements on effiectively enumerable T0-spaces which guarantee that the Rice-Shapiro theorem holds for the computable elements of these spaces. We show that the relaxation of these requirements leads to the classes of effiectively enumerable T0-spaces where the Rice-Shapiro theorem does not hold. We propose two constructions that generate effiectively enumerable T0-spaces with particular properties from wn-families and computable trees without computable infinite paths. Using them we propose examples that give a flavor of this class. © M. Korovina and O. Kudinov.
