    • Fibrant presheaves of spectra and Guillen-Navarro extension 

      Rubió Pons, Llorenç (2009)
      Article
      Accés obert
      In this remark we prove that the Guill´en-Navarro extension of a presheaf of spectra in the category of algebraic varieties over a field of characteristic zero, when exists, coincides up to weak equivalence with the ...

    • Model categories and cubical descent 

      Rubió Pons, Llorenç (2007-06-12)
      Article
      Accés obert
      We prove that the subcategory of fibrant objects of a simplicial model category is a cohomological descent category, in the sense of Guillén and Navarro, if and only if an acyclicity criterion holds.

    • Stable model categories and cohomological descent 

      Rubió Pons, Llorenç (2006-07-28)
      Article
      Accés obert
      We prove that the subcategory of fibrant objects of a stable simplicial model category is a cohomological descent category, in the sense of Guillén and Navarro.
