@article {26179, title = {Coordinates for non-integrable Lie algebroids}, year = {Forthcoming}, abstract = {We construct local coordinates for the Weinstein groupoid of a non-integrable Lie algebroid. To this end, we reformulate the notion of bi-submersion in a completely algebraic way and prove the existence of bi-submersions as such for the Weinstein groupoid. This implies that a C*-algebra can be attached to every Lie algebroid.}, url = {https://arxiv.org/abs/2106.12002}, author = {Iakovos Androulidakis} }
