Motivic HyperKähler Resolution Conjecture for global quotients

Let MM be a smooth projective holomorphic symplectic variety equipped with a faithful action of a finite group GG by symplectic automorphisms of MM. If YY is a symplectic resolution of the quotient variety M/GM/G, then the Motivic HyperKähler Resolution Conjecture. there is an isomorphism of commutative algebra objects in the category of Chow motives with complex coefficients,

h(Y)horb([M/G])in CHMC,\mathfrak h(Y)\simeq \mathfrak h_{\operatorname{orb}}([M/G])\quad\text{in }\operatorname{CHM}_{\mathbb C},

and, in particular, an isomorphism of graded C\mathbb C-algebras

CH(Y)CCHorb([M/G])C.\operatorname{CH}^*(Y)_{\mathbb C}\simeq \operatorname{CH}^*_{\operatorname{orb}}([M/G])_{\mathbb C}.

This is the precise global-quotient form of the motivic resolution conjecture studied in the paper; the supplied source gives no resolution of it in general.
