  • Fibrant presheaves of spectra and Guillen-Navarro extension 

    Rubió Pons, Llorenç (2009)
    Article
    Open Access
    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
    Open Access
    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

    Article
    Open Access
    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.
