Brauer Groups, Tamagawa Measures, and Rational Points on Algebraic Varieties
Share this pageJörg Jahnel
The central theme of this book is the study of rational points on
algebraic varieties of Fano and intermediate type—both in terms of
when such points exist and, if they do, their quantitative
density. The book consists of three parts. In the first part, the
author discusses the concept of a height and formulates Manin's
conjecture on the asymptotics of rational points on Fano varieties.
The second part introduces the various versions of the Brauer
group. The author explains why a Brauer class may serve as an
obstruction to weak approximation or even to the Hasse principle. This
part includes two sections devoted to explicit computations of the
Brauer–Manin obstruction for particular types of cubic surfaces.
The final part describes numerical experiments related to the Manin
conjecture that were carried out by the author together with
Andreas-Stephan Elsenhans.
The book presents the state of the art in computational arithmetic
geometry for higher-dimensional algebraic varieties and will be a
valuable reference for researchers and graduate students interested in
that area.
