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…

Differential operators and actions of Lie algebroids

Y. Kosmann-Schwarzbach, K. C. H. Mackenzie

We demonstrate that the notions of derivative representation of a Lie algebra on a vector bundle, of semi-linear representations of a Lie group on a vector bundle, and related conc…

Quasi-Poisson Manifolds

Anton Alekseev, Yvette Kosmann-Schwarzbach, Eckhard Meinrenken

A quasi-Poisson manifold is a G-manifold equipped with an invariant bivector field whose Schouten bracket is the trivector field generated by the invariant element in $\wedge^3 \g$

Quantum homogeneous spaces and quasi-Hopf algebras

B. Enriquez, Y. Kosmann-Schwarzbach

We propose a formulation of the quantization problem of Manin quadruples, and show that a solution to this problem yields a quantization of the corresponding Poisson homogeneous sp…

Manin pairs and moment maps

Anton Alekseev, Yvette Kosmann-Schwarzbach

A Lie group G in a group pair (D,G), integrating a Lie algebra g in a Manin pair (d,g) has a quasi-Poisson structure. We define the quasi-Poisson actions of such Lie groups G, that…
