Algebraic K-theory and cubical descent
Pascual Gainza, Pere; Rubió Pons, Llorenç (2009)
Article
Accés obertIn this note we apply the Guillén-Navarro descent theorem to define a descent variant of the algebraic K-theory of varieties over a field of characteristic zero, KD(X), which coincides with K(X) for smooth varieties and ... -
Categories de descens: aplicacions a la teoría K algebraica
Rubió Pons, Llorenç (Universitat Politècnica de Catalunya, 2008-07-08)
Tesi
Accés obertEn el marc de l'estudi de la cohomologia de les varietats algebraiques, i en particular en les aplicacions cohomològiques del teorema de resolució de singularitats d'Hironaka, utilitzem la tècnica de les hiperresolucions ... -
Fibrant presheaves of spectra and Guillen-Navarro extension
Rubió Pons, Llorenç (2009)
Article
Accés obertIn 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 obertWe 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 obertWe 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.
