Morita invariance of intrinsic characteristic Classes of Lie algebroids

In this note, we prove that intrinsic characteristic classes of Lie algebroids { which in degree one recover the modular class { behave functorially with respect to arbitrary transverse maps, and in particular are weak Morita invariants. In the modular case, this result appeared in [Kosmann-Schwarzb...

Sumario:In this note, we prove that intrinsic characteristic classes of Lie algebroids { which in degree one recover the modular class { behave functorially with respect to arbitrary transverse maps, and in particular are weak Morita invariants. In the modular case, this result appeared in [Kosmann-Schwarzbach Y., Laurent-Gengoux C., Weinstein A., Trans- form. Groups 13 (2008), 727{755], and with a connectivity assumption which we here show to be unnecessary, it appeared in [Crainic M., Comment. Math. Helv. 78 (2003), 681{721] and [Ginzburg V.L., J. Symplectic Geom. 1 (2001), 121{169].
