Blowups of Dirac structures

Ioan Marcut, Andreas Schüßler, Marco Zambon

Given a real, twisted Dirac structure $L$ on a smooth manifold $M$ , and a closed embedded submanifold $N \subseteq M$ of codimension $> 1$ , we characterise when $L$ lifts to a smooth…

Poisson structures with compact support

Gil R. Cavalcanti, Ioan Marcut

We explicitly construct several Poisson structures with compact support. For example, we show that any Poisson structure on $R^{n}$ with polynomial coefficients of degree at most tw…

Poisson structures whose Poisson diffeomorphism group is not locally path-connected

Ioan Marcut

We build examples of Poisson structure whose Poisson diffeomorphism group is not locally path-connected.

The Poisson cohomology of $sl_{2}^{*} (R)$

Ioan Marcut, Florian Zeiser

We compute the smooth Poisson cohomology of the linear Poisson structure associated with the Lie algebra $sl_{2}^{*} (R)$ .
