Stratified vector fields on orbit spaces
Mateus de Melo, Juan Sebastian Herrera-Carmona, Fabricio Valencia
Using Morita type stratifications, we establish a one-to-one correspondence between geometric vector fields on a separated differentiable stack and stratified vector fields on its…
Vector fields and derivations on differentiable stacks
Juan Sebastian Herrera-Carmona, Cristian Ortiz, James Waldron
We introduce and study module structures on both the dgla of multiplicative vector fields and the graded algebra of functions on Lie groupoids. We show that there is an associated…
The Chern-Weil-Lecomte characteristic map for -algebras
Juan Sebastian Herrera-Carmona, Cristian Ortiz
In this paper we extend the Chern-Weil-Lecomte characteristic map to the setting of -algebras. In this general framework, characteristic classes of -algebra…
Isometric Lie 2-group actions on Riemannian groupoids
Juan Sebastian Herrera-Carmona, Fabricio Valencia
We study isometric actions of Lie -groups on Riemannian groupoids by exhibiting some of their immediate properties and implications. Firstly, we prove an existence result which…
