Weil Groups and F-isocrystals
28 mai 2025 - 15:30Salle de séminaires IRMA
Résumé en anglais : We give an explicit construction of the fundamental class of a Galois extension of local fields, based on the Dieudonne-Manin structure theorem for F-isocrystals. This makes possible an elementary derivation of the basic results of local class field theory.
