## Abstract We investigate connections between the syntactic and semantic distance of programs on an abstract, recursion theoretic level. For a certain rather restrictive notion of interdependency of the two kinds of distances, there remain only few and βunnaturalβ numberings allowing such close re
Let (DS, DQ, sim) be a retrieval system consisting of a document space DS, a query space QS, and a function sim, expressing the similarity between a document and a query. Following D. M. Everett and S. C. Cater (1992), we introduce topologies on the document space. These topologies are generated by
The paper deals with (effective) descent morphisms for subfibrations E(X) of the basic fibration Top~X, for topological spaces X and classes E of continuous functions stable under pullback. For a category with pullbacks, we prove the stability under pullback of effective Edescent morphisms for a cla
