Number fields

Daniel A. Marcus0387902791, 9780387902791

Requiring no more than a basic knowledge of abstract algebra, this text presents the mathematics of number fields in a straightforward, “down-to-earth” manner. It thus avoids local methods, for example, and presents proofs in a way that highlights the important parts of the arguments. Readers are assumed to be able to fill in the details, which in many places are left as exercises.
