%0 Journal Article %T VB-algebroid morphisms and representations up to homotopy %A Thiago Drummond %A Madeleine Jotz %A Cristian Ortiz %J Mathematics %D 2013 %I arXiv %X We show in this paper that the correspondence between 2-term representations up to homotopy and $\mathcal{VB}$-algebroids, established by Gracia-Saz and Mehta, holds also at the level of morphisms, proving in particular that such correspondence is an equivalence of categories. As an application we study the relationship between IM-foliations on a Lie algebroid $A$ (the infinitesimal notion of ideal systems) and subrepresentations of the adjoint representation of $A$. %U http://arxiv.org/abs/1302.3987v1
