[Cohomologie de déformation d'un algèbroïde de Lie et équivalence de Morita]
Comptes Rendus. Mathématique, Volume 356 (2018) no. 4, pp. 376-381.

Soit AM un algébroïde de Lie. Dans cette note, nous prouvons qu'un pull-back de A lelong d'une fibration ayant des fibres homologiquement m-connexes possède la même cohomologie de déformation que A jusqu'au degré m.

Let AM be a Lie algebroid. In this short note, we prove that a pull-back of A along a fibration with homologically m-connected fibers shares the same deformation cohomology of A up to degree m.
