Proposition 3.10. There is a weight structure ww on DTMG⁡(k,ℚ)\operatorname{DTM}_{G}(k,\mathbb{Q}) such that

M∈DTMG⁡(k,ℚ)w≥0\displaystyle M\in\operatorname{DTM}_{G}(k,\mathbb{Q})^{w\geq 0} ⇔For⁡(M)∈DTM⁡(k,ℚ)w≥0​ and\displaystyle\iff\operatorname{For}(M)\in\operatorname{DTM}(k,\mathbb{Q})^{w\geq 0}\text{ and }
M∈DTMG⁡(k,ℚ)w≤0\displaystyle M\in\operatorname{DTM}_{G}(k,\mathbb{Q})^{w\leq 0} ⇔For⁡(M)∈DTM⁡(k,ℚ)w≤0.\displaystyle\iff\operatorname{For}(M)\in\operatorname{DTM}(k,\mathbb{Q})^{w\leq 0}.
