      It is natural to extend the Grothendieck Theorem on completeness, valid for locally convex topological vector spaces, to abelian topological groups. The adequate framework to do it seems to be the class of locally ...

      [ANGLÈS] We present such aspects of beam propagation as the double focalization, the dependence of focusing on frequency, and the effects of a limited numerical aperture of this lens.
    • Strong reflexivity of Abelian groups 

      Bruguera Padró, Maria Montserrat; Chasco Ugarte, Maria Jesús (1998)

      A reflexive topological group G is called strongly reflexive if each closed sub-group and each Hausdorff quotient of the group G and of its dual group is reflexive. In this paper we establish the adequate concept of strong ...
