每个投射Schur代数都与一个radical交换代数Brauer等价

Every projective Schur algebra is Brauer equivalent to a radical abelian algebra

Eli Aljadeff, Ángel del Río

摘要:

证明了域$K$上的任意投射Schur代数在$Br(K)$中等价于根交换代数.这是1995年由Sonn和本文的第一作者提出的。作为结果,我们得到了一个特征的投射舒尔群的伽罗瓦上同调。该猜想是已知的代数领域的积极特征。在特征为零的猜想是已知的代数域上的亨塞尔估值的局部或整体领域的特征为零。

英文摘要:

We prove that any projective Schur algebra over a field $K$ is equivalent in $Br(K)$ to a radical abelian algebra. This was conjectured in 1995 by Sonn and the first author of this paper. As a consequence we obtain a characterization of the projective Schur group by means of Galois cohomology. The conjecture was known for algebras over fields of positive characteristic. In characteristic zero the conjecture was known for algebras over fields with an Henselian valuation over a local or global field of characteristic zero.
