论文摘要
在本说明中，我们通过$ a^1 $ - homotopy类别中一些Eienberg-Maclane空间的光滑投影性品种构造近似值。使用这些，我们研究了从盘环到依托共同学环的循环图。
In this note we construct approximations by smooth projective varieties of some Eienberg-MacLane spaces in the $A^1$-homotopy category. Using these, we study the cycle maps from Chow rings to etale cohomology rings.
