A remark on the linearization of nondegenerate Nambu structures of coorder 1
Florian Zeiser
In this note we show that Nambu structures of coorder 1 can always be linearized if they admit a closed integrable differential form. In particular, we show that a unimodular Poiss…

Formal Poisson (co)homology of the Lefschetz singularity
Lauran Toussaint, Florian Zeiser
We compute the formal Poisson cohomology groups of a real Poisson structure on associated to the Lefschetz singularity . In partic…

Infinitesimally rigid Lie foliations with dense leaves
Stephane Geudens, Florian Zeiser
We call a foliation on a compact manifold infinitesimally rigid if its deformation cohomology vanishes. This paper studies infinites…
