Relative modular classes of Lie algebroids
Yvette Kosmann-Schwarzbach, Alan Weinstein
We study the relative modular classes of Lie algebroids, and we determine their relationship with the modular classes of Lie algebroids with a twisted Poisson structure.

The modular class of a twisted Poisson structure
Yvette Kosmann-Schwarzbach, Camille Laurent-Gengoux
We study the geometric and algebraic properties of the twisted Poisson structures on Lie algebroids, leading to a definition of their modular class and to an explicit determination…
