Conference: Linear algebraic groups and cohomology

这笔赠款为2007年5月16-20日在埃默里大学举行的“线性代数群和上同调”会议提供了支持。会议的主题是一般地面上的线性代数群。会议的一些主要主题是上同调不变量；扭量的数值不变量；齐次空间上的有理点；曲面和分支数据上的除代数；以及Chow群和Movic分解。由于代数几何中新方法的应用，关于这些主题的研究成果不断涌现。这次会议建立在之前在欧洲成功举办的一系列会议的基础上。它将为美国人出席通常需要国际旅行的会议提供一个方便的论坛。有关会议的更多信息，请访问会议网站：http://www.mathcs.emory.edu/~skip/LAGC07

This grant provides support for the conference "Linear algebraic groups and cohomology" held at Emory University during 16-20 May 2007. The subject of the conference is linear algebraic groups over a general ground field.Some main themes of the conference are cohomological invariants; numerical invariants of torsors; rational points on homogeneous spaces; division algebras over surfaces and ramification data; and Chow groups and motivic decomposition. There is an ongoing explosion of results on these topics stemming from applications of new methods from algebraic geometry.This conference builds on a series of previous successful conferences in Europe. It will provide a convenient forum for US persons to attend a conference of a type that would normally demand international travel.More information about the conference can be found on the conference website at http://www.mathcs.emory.edu/~skip/LAGC07
