Fix a semisimple conjugacy class $\Psi$ in $G$, choose $h\in\Psi$, and let $Z={\mathcal Z}_G(h)$. For every separated $G$-space $X$, let…

Suppose $X$ is a smooth variety of dimension $d$ equipped with a $G$-action. Let $(X,\Delta_X)_G$ be its equivariant Chow motive, and let an equivariant Chow–Künneth decomposition…
