The shifted symplectic geometry of derived higher groupoids
Miquel Cueca, Florian Dorsch, Reyer Sjamaar +1
The main goal of this work is to introduce derived Lie n-groupoids and their shifted symplectic structures. We further define shifted lagrangian structures and prove that their com…

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…
