Description

This lecture covers the uniqueness of norm extension in finite fields, focusing on the Galois property and prime fields. It explains the construction of norms on finite extensions of Qp, emphasizing the existence of at most one field norm extending the one on F. The instructor discusses the concept of norms on finite extensions, the cyclic group of order q-1, and the extension of norms. The lecture concludes with the definition of the norm of a field-linear endomorphism and the application of norms in finite fields.
