Algebraic integrability and minimality of Lie equations for transitive, finite dimensional, non-commutative pseudogroups
Alejandro Arenas Tirado, David Blázquez-Sanz, Guy Casale
We provide an algebraic characterization of transitive, finite-dimensional algebraic Lie pseudogroups (or -groupoids) that are algebraic integrable, that is, isogenous…

Group bundles and group connections
David Blázquez-Sanz, Carlos A. Marín-Arango, Sedney Suárez Gordon
We consider smooth families of Lie groups (group bundles) and connections that are compatible with the group operation. We characterize the space of group connections on a group bu…
