Abstract
Any Lie algebroid admits a Nash-type blow-up that sits in a nice short exact sequence of Lie algebroids with a Lie algebra bundle and a Lie algebroid whose anchor map is injective on an open dense subset. The base variety is a blowup determined by the singular foliation of . We provide concrete examples. Moreover, we extend the construction following Mohsen's to singular subalgebroids in the sense of Androulidakis-Zambon.
