We investigate conditions varying on VV(x): x E X, where each ~V(z) is a countable family of subsets containing x. Characterizations and mapping properties of them are obtained. New criteria for a-spaces arc given.

## Abstract Every secondβcountable regular topological space __X__ is metrizable. For a given βcomputableβ topological space satisfying an axiom of computable regularity M. SchrΓΆder [10] has constructed a computable metric. In this article we study whether this metric space (__X, d__) can be consid
## Abstract In the spirit of the classical random central limit theorem a general limit theorem for random stopping in the scheme of infinitesimal triangular arrays on a separable metrizable group is presented. The approach incorporates and generalizes earlier results for normalized sequences of in
The notions of a weak k-development and of a weak development, defined in terms of sequences of open covers, were recently introduced by the first and the third authors. The first notion was applied to extend in an interesting way Michael's Theorem on double set-valued selections. The second notion
