Hi, do someone have patience to explain how is the Lie differentiation of -Lie groupoids? More precisely, I’m assuming that a -Lie groupoid is a simplicial manifold satisfying the usual Kan fibrancy assumption (the restriction from n-simplices to the i-th horn is a surjective submersion) as in http://arxiv.org/abs/math/0603563 . However in nlab, as I understand, it’s assumed a more general case in the cohesive synthetic setting (which I know almost nothing about and apparently is not so explicit) using infinitesimally thickened simplexes. Is there a more explicit construction that differentiate a Lie groupoid (in the sense described above) to an -Lie algebroid? Maybe an illustrative example would be how to make this construction using the nerve of an ordinary Lie groupoid to obtain the usual Lie algebroid (as a cochain complex concentrated in degreee 1).
Thanks in advance.
