Relative Poisson cohomology conjecture. Let $pi$ be a Poisson structure with a compact symplectic leaf $S\subset M$. If

Let $I(\Omega)$ be the ring of $G$-invariant smooth functions on $\Omega$, and let $H_{\Lambda,\operatorname{tan}}^1(\Omega)$ denote the first tangential Poisson cohomology of the…

Let $B=(b_{ij})_{i,j=0}^{n-1}$ be a biresidue matrix. It is holonomic if, for every subset $J\subset\{0,1,\dots,n-1\}$ of odd cardinality, the linear span of the rows of the submat…
