Flatness of contravariant connections
In general, it is not possible to find parallel frames for a flat contravariant connection, even if the Poisson structure is regular.
As an example, let $\pi$ be the zero Poisson structure on a manif …

Hypersurfaces with Gorenstein singular loci
Recall that a hypersurface $D$ in a complex manifold $X$ is called a free divisor if the Lie algebroid $\mathcal{T}_X(-\log D)$ of vector fields tangent to $D$ is locally free. This condition is equi …
