附于双扩张的度量群

Metric groups attached to biextensions

Swarnendu Datta

摘要:

设$G$是特征p > 0的代数闭域上的连通幂幺完满群群概型. V. Drinfeld定义了一个度量群,该度量群通过离散群$Q_p/Z_p$与$G \times G$的双扩张相关联。证明了Drinfeld关于这个度量群在Witt群中的类的一个猜想。

英文摘要:

Let $G$ be a connnected, unipotent, perfect group scheme over an algebraically closed field of characteristic p > 0. V. Drinfeld has defined a certain metric group associated to biextensions of $G \times G$ by the discrete group $Q_p/Z_p$. We prove a certain conjecture of Drinfeld regarding the class of this metric group in the Witt group.
