我们表明,在适当的代数空间$X$的温和的假设下,函子采取其对称的权力和它的\'{e}tale实现交换弱等价。我们得出了一个有效的版本的Dold-Thom定理的\'{e}tale网站和讨论的稳定性结果的自然态射的\'{e}tale同伦群$\pi_k \mathrm {Sym}^n X \to \pi_k \mathrm{Sym}^{n+1} X$的上下文中的Weil结构。
We show that under mild hypotheses on a proper algebraic space $X$, the functors of taking its symmetric powers and its \'{e}tale realisation commute up to weak equivalence. We conclude an effective version of the Dold-Thom theorem for the \'{e}tale site and discuss the stabilisation results for the natural morphisms of \'{e}tale homotopy groups $\pi_k \mathrm{Sym}^n X \to \pi_k \mathrm{Sym}^{n+1} X$ in the context of the Weil conjectures.
