主讲人： Jean-Louis Colliot-Thelene (CNRS & Universite Paris Sud)
活动时间： 从 2015-11-03 00:00 到 2015-11-24 00:00
场地： 一教208
Time: Nov. 3, 10, 17, 24 3:10-6:00
Summary:
The Brauer group of algebraic varieties features prominently in at least two directions of research:
birational problems (the L¨uroth problem) and arithmetic geometry (Brauer-Manin obstruction).
The November 2015 lectures will be devoted to the algebraic theory of the Brauer group. The first
part will be devoted to the general properties of the Brauer group. The second part will be concerned with
concrete computations of the Brauer group for various classes of algebraic varieties.
