Remarks on the structure and integrability of LA-groups
Camilo Angulo
We study the structure of an LA-group identifying its underlying VB-group with a representation up to homotopy. We show that the Lie algebroid structure is determined by a compleme…

The van Est homomorphism for strict Lie 2-groups
Camilo Angulo, Miquel Cueca
We construct a van Est map for strict Lie 2-groups from the Bott-Shulman-Stasheff double complex of the strict Lie 2-group to the Weil algebra of its associated strict Lie 2-algebr…
