关于正特征的泛稳定自由模
On universal stably free modules in positive characteristic
摘要：
在不限制基场特征的情况下，研究了在Steenrod算子作用下，齐次簇如$GL_{n}/GL_{r}$或$Sp_{2n}/Sp_{2n-2}$的模$p$模上同调.特别是，我们证明了某些商映射不承认部分。
英文摘要：
We study the mod $p$ motivic cohomology of homogeneous varieties such as $GL_{n}/GL_{r}$ or $Sp_{2n}/Sp_{2n-2}$ along with the action of the Steenrod operations, without restrictions on the characteristic of the base field. In particular, we prove that certain quotient maps do not admit sections.
