From double Lie groupoids to local Lie 2-groupoids
Rajan Amit Mehta, Xiang Tang
We apply the bar construction to the nerve of a double Lie groupoid to obtain a local Lie 2-groupoid. As an application, we recover Haefliger's fundamental groupoid from the fundam…

VB-groupoids and representation theory of Lie groupoids
Alfonso Gracia-Saz, Rajan Amit Mehta
A VB-groupoid is a Lie groupoid equipped with a compatible linear structure. In this paper, we describe a correspondence, up to isomorphism, between VB-groupoids and 2-term represe…
