A model for non-free circle actions
(1997)
Article
Accés obertLet $\Phi: \Bbb S^{1}\times M\longrightarrow M$ be a smooth action of the unit circle $\Bbb S^{1}$ on a manifold $M$. In this work, we compute the minimal model of $M$ in terms of the orbit space $B$ and the fixed point ... -
Godement resolutions and sheaf homotopy theory
(2014-09)
Article
Accés restringit per política de l'editorialThe Godement cosimplicial resolution is available for a wide range of categories of sheaves. In this paper we investigate under which conditions of the Grothendieck site and the category of coefficients it can be used to ... -
Homotopy Batalin-Vilkovisky algebras
(2011-03-30)
Altres
Accés obertThis paper provides an explicit cofibrant resolution of the operad encoding Batalin-Vilkovisky algebras. Thus it defines the notion of homotopy Batalin-Vilkovisky algebras with the required homotopy properties. To define ... -
Homotopy Gerstenhaber structures and vertex algebras
(2010)
Article
Accés obertWe provide a simple construction of a G∞-algebra structure on an important class of vertex algebras V, which lifts the Gerstenhaber algebra structure on BRST cohomology of V introduced by Lian and Zuckerman. We outline two ... -
Homotopy linear algebra
(2016-02)
Report de recerca
Accés obertBy homotopy linear algebra we mean the study of linear functors between slices of the 8-category of 8-groupoids, subject to certain finiteness conditions. After some standard definitions and results, we assemble said slices ... -

Introducció als tipus d'homotopia d'ordre superior a 1: grups d'homotopia de conjunts simplicials
(Universitat Politècnica de Catalunya, 2023-06-20)
Treball Final de Grau
Accés obertEls grups d'homotopia s'utilitzen en la topologia algebraica per classificar els espais topològics. Mitjançant l'associació de grups amb espais topològics i emprant les valuoses eines de la teoria de grups, enregistren ... -
Model categories and cubical descent
(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. -
Some remarks on Cartan-Eilenberg categories
(2012-05)
Article
Accés restringit per política de l'editorialIn this note we collect some remarks and examples on Cartan–Eilenberg categories. -
Sparse methods for Online Support Vector Machine
(Universitat Politècnica de Catalunya, 2014-11-28)
Projecte Final de Màster Oficial
Accés obertAquest treball proposa un nou classificador online basat en Kernel SVM que minimitza el nombre de vectors de suport gràcies una restricció adicional imposada mitllançant métodes de continuació. Conseqüentment, es pot fer ... -
The groupoid of finite sets is biinitial in the 2-category of rig categories
(2021-11-01)
Article
Accés obertThe groupoid of finite sets has a “canonical” structure of a symmetric 2-rig with the sum and product respectively given by the coproduct and product of sets. This 2-rig ^ FSet is just one of the many non-equivalent ... -
Up-to-homotopy algebras with strict units
(2018-12-20)
Report de recerca
Accés obertWe prove the existence of minimal models à la Sullivan for operads with non trivial arity zero. So up-to-homotopy algebras with strict units are just operad algebras over these minimal models. As an application we give ...
