• openAccess   Contributions to the Bohr topology by W.W. Comfort 

      Hernández, Salvador; Remus, Dieter; Trigos, Javier Elsevier (2019)
      The important rôle that W. W. Comfort played in the study of the Bohr topology is described.
    • openAccess   On closed subgroups of precompact groups 

      Hernández, Salvador; Remus, Dieter; Trigos, Javier De Gruyter (2022-09-28)
      It is a Theorem of W. W. Comfort and K. A. Ross that if G is a subgroup of a compact Abelian group, and S denotes those continuous homomorphisms from G to the one-dimensional torus, then the topology on G is the initial ...
    • openAccess   Topological Methods in Analysis (Editorial) 

      Hernández, Salvador; Narici, Lawrence; Trigos, Javier Hindawi Publishing Corporation (2013)
      Topological methods have played a seminal role in functional analysis since its birth in the early twentieth century. The Baire category theorem, for example, is the bedrock on which rest such basic principles of functional ...
    • closedAccess   Uncountable products of determined groups need not be determined 

      Hernández, Salvador; Macario, Sergio; Trigos, Javier Elsevier (2008)
      If H is a dense subgroup of G, we say that H determines G if their groups of characters are topologically isomorphic when equipped with the compact open topology. If every dense subgroup of G determines G, then we say that ...
    • openAccess   When a totally bounded group topology is the Bohr topology of a LCA group 

      Hernández, Salvador; Trigos, Javier Elsevier (2019-06-01)
      We look at the Bohr topology of maximally almost periodic groups (MAP, for short). Among other results, we investigate when a Hausdorff precompact abelian group (G; w) is the Bohr re ection of a locally compact abelian ...
