In the framework of effectively enumerable topological spaces, we investigate the following question: given an effectively enumerable topological space whether there exists a computable numbering of all its computable elements. We present a natural sufficient condition on the family of basic neighborhoods of computable elements that guarantees the existence of a principal computable numbering. We show that weakly-effective–continuous domains and the natural numbers with the discrete topology satisfy this condition. We prove weak and strong analogues of Rice’s theorem for computable elements.
