    • openAccess   Balleans of topological groups 

      Hernández, Salvador; Protasov, I. Springer Verlag (2011)
      A subset S of a topological group G is called bounded if, for every neighborhood U of the identity of G, there exists a finite subset F such that S ⊆ FU, S ⊆ UF. The family of all bounded subsets of G determines two ...

    • closedAccess   Completions of paratopological groups and bounded sets 

      Sanchis López, Manuel; Tkachenko, Mikhail Springer Verlag (2017)
      In this paper we consider two questions in the realm of paratopological groups: When does multiplication on a given Tychonoff paratopological group H admit an extension to continuous multiplication on the Dieudonné ...

    • closedAccess   Moscow spaces and selection theory 

      Sanchis López, Manuel Elsevier (2008)
      A well-known result on Moscow spaces states that every G<sub>δ</sub>-dense subset of a Moscow space X is C-embedded in X. We present here the selection version of this result and also (by means of two different approaches) ...
