Abstract

The notion of class formation was introduced by Artin-Tate [8] after earlier work by Weil [67] and by Hochschild-Nakayama [36]. This notion clarifies the cohomological aspect of class field theory, both in the local and the global cases. The present chapter is restricted to the main properties of class formations; the reader will find in Artin-Tate [8] further developments (the Šafarevič theorem, Weil groups).
