On the regular representation of an (essentially) finite 2-group
Elgueta Montó, Josep (2010-12-01)
Report de recerca
Accés obertThe regular representation of an essentially finite 2-group $\mathbb{G}$ in the 2-category $\mathbf{2Vect}_k$ of (Kapranov and Voevodsky) 2-vector spaces is defined and cohomology invariants classifying it computed. It is ... -

On the representations of 2-groups in Baez-Crans 2-vector spaces
Alarcón Heredia, Benjamín; Elgueta Montó, Josep (2016-10-06)
Article
Accés obertWe study the theory of representations of a 2-group G in Baez-Crans 2-vector spaces over a field k of arbitrary characteristic, and the corresponding 2-vector spaces of intertwiners. We also characterize the irreducible ... -
Permutation 2-groups I: structure and splitness
Elgueta Montó, Josep (2014-06-20)
Article
Accés obertBy a 2-group we mean a groupoid equipped with a weakened group structure. It is called split when it is equivalent to the semidirect product of a discrete 2-group and a one-object 2-group. By a permutation 2-group we mean ... -
The 2-group of symmetries of a split chain complex
Elgueta Montó, Josep (2010-12-15)
Report de recerca
Accés obertWe explicitly compute the 2-group of self-equivalences and (homotopy classes of) chain homotopies between them for any {\it split} chain complex $A_{\bullet}$ in an arbitrary $\kb$-linear abelian category ($\kb$ any ... -
The groupoid of finite sets is biinitial in the 2-category of rig categories
Elgueta Montó, Josep (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 ... -
