The Poisson-de Rham homology conjecture for affine symplectic resolutions

Let ρ:X~X\rho:\widetilde X\to X be a symplectic resolution, with XX affine, and let HPiDR(X)\operatorname{\mathsf{HP}}_i^{DR}(X) denote the Poisson-de Rham homology of XX. The affine symplectic-resolution conjecture. One has

HP0(O(X))HdimX(X~),\operatorname{\mathsf{HP}}_0(\mathcal O(X))\cong H^{\dim X}(\widetilde X), HPiDR(X)HdimXi(X~)for all i,\operatorname{\mathsf{HP}}_i^{DR}(X)\cong H^{\dim X-i}(\widetilde X)\quad\text{for all }i,

and

M(X)ρΩX~.M(X)\cong\rho_*\Omega_{\widetilde X}.

The three assertions give a conjectural description of Poisson-de Rham homology for affine varieties admitting symplectic resolutions, and relate it to the ordinary cohomology of the resolution. The supplied text does not establish a resolution status for this bundled conjecture; the database therefore records it as open.
