The Trace and Norm for a Galois extension - UCONN

The Trace and Norm for a Galois extension Let L=Kbe a nite Galois extension, with Galois group G= Gal(L=K). We can express characteristic polynomials, traces, and norms for the extension L=Kin terms of G. Theorem 1.1. When L=Kis a nite Galois extension with Galois group Gand 2L, ... From Galois theory,

THE CHINESE REMAINDER THEOREM - UCONN

The Chinese remainder theorem says we can uniquely solve any pair of congruences that have relatively prime moduli. Theorem 1.1. Let m and n be relatively prime positive integers. For any integers a and b, the pair of congruences x a mod m; x b mod n
