Double groupoid cohomology and extensions
Jesús Alonso Ochoa Arango, Alejandro Tiraboschi
We study extensions of double groupoids in the sense of \cite{AN2} and show some classical results of group theory extensions in the case of double groupoids. For it, given a doubl…
Automorphisms of non-singular nilpotent Lie algebras
Aroldo Kaplan, Alejandro Tiraboschi
For a real, non-singular, 2-step nilpotent Lie algebra , the group \Aut(\mathfrak{n})/\Aut_0(\mathfrak{n})\Aut_0(\mathfrak{n})$ is the group of automorphism…
Multiplier Infinitesimal Bialgebras and Derivator Lie Bialgebras
Jesus Alonso Ochoa Arango, Alejandro Tiraboschi, Shuanhong Wang
We propose a definition of multiplier infinitesimal bialgebra and a definition of derivator Lie bialgebra. We give some examples of these structures and prove that every bibalanced…
On slim double Lie groupoids
Nicolas Andruskiewitsch, Jesus Alonso Ochoa Arango, Alejandro Tiraboschi
We prove that every slim double Lie groupoid with proper core action is completely determined by a factorization of a certain canonically defined "diagonal" Lie groupoid.
A family of Poisson non-compact symmetric spaces
Nicolas Andruskiewitsch, Alejandro Tiraboschi
We study Poisson symmetric spaces of group type with Cartan subalgebra "adapted" to the Lie cobracket.
Horizontal submanifolds of groups of Heisenberg type
A. Kaplan, F. Levstein, L. Saal +1
We study maximal horizontal subgroups of Carnot groups of Heisenberg type. We classify those of dimension half of that of the canonical distribution ("lagrangians") and illustrate…
