    • Characterization, definability and separation via saturated models 

      Areces, Carlos Eduardo; Carreiro, Facundo; Figueira, Santiago (2014)

    • Completeness in hybrid type theory 

      Areces, Carlos Eduardo; Blackburn, Patrick; Huertas, Antonia; Manzano, María (2014)
      We show that basic hybridization (adding nominals and @ operators) makes it possible to give straightforward Henkin-style completeness proofs even when the modal logic being hybridized is higher-order. The key ideas are ...

    • Examples of pointed color Hopf algebras 

      Andruskiewitsch, Nicolás; Angiono, Iván Ezequiel; Bagio, Dirceu (2014)
      We present examples of color Hopf algebras, i.e. Hopf algebras in color categories (braided tensor categories with braiding induced by a bicharacter on an abelian group), related with quantum doubles of pointed Hopf algebras. ...
    • Existence of strictly positive solutions for sublinear elliptic problems in bounded domains 

      Godoy, Tomás Fernando; Kaufmann, Uriel (2014)
