Название: Brauer Groups, Hopf Algebras and Galois Theory
Автор: Caenepeel S.
The development of the theory of the Brauer group of a field began around 1930; the underlying idea is to study properties of central simple algebras by considering them as representatives of elements of the Brauer group. It became clear that the Brauer group of a field is an important invariant, often reflecting arithmetic properties of the groundfield k...
