    • openAccess   A classification of the cofinal structures of precompacta 

      Eshed, Aviv; Ferrer González, María Vicenta; Hernández, Salvador; Szewczak, Piotr; Tsaban, Boaz Elsevier (2020-08)
      We provide a complete classification of the possible cofinal structures of the families of precompact (totally bounded) sets in general metric spaces, and compact sets in general complete metric spaces. Using this ...

    • openAccess   The character of topological groups, via Pontryagin-van Kampen duality 

      Chis, Cristina; Ferrer González, María Vicenta; Hernández, Salvador; Tsaban, Boaz (2011-06)
      The Birkhoff-Kakutani Theorem asserts that a topological group is metrizable if and only if it has countable character. We develop and apply tools for the estimation of the character for a wide class of nonmetrizable ...
