Some aspects of the theory of quadratic forms over a field
Jeudi, 23 Mai, 2024 - 16:30
Résumé : 
In this talk, we will give an overview of the (basic aspects of the) theory of quadratic forms. We would like to introduce some constructions used to study these objects like Witt rings and function fields; see some invariants such as u-invariants and Clifford algebras; and treat in particular the case of quadratic forms over the field Q of rational numbers.
