Rains numbfr, Neil J. Throughout, the authors emphasise the systematic development of techniques for the explicit Cambridge University PressFeb 4, – Mathematics – pages. The drawback is that the local and adelic theories are nowhere to be found in this book.
My library Help Advanced Book Search. Function fields and number fields are treated on an essentially equal footing here. Extensive, but perhaps not great for beginners.
VIII4 Primes in an arithmetic progression. Uses local fields and adeles heavily.
It is very readable, and the last chapter motivates class field theory nicely. TaylorMartin J. It does not use cohomology. I2 Integrality and Noetherian properties. The basics are covered very quickly, however.
These notes also contain useful references. It provides a brisk, thorough treatment of the foundations of algebraic number theory, and builds on that to introduce more advanced ideas.
I lectured on these during our first two meetings. III2 Discriminants and differents. Algebraic Number Theory A. This book originates from graduate courses given in Nu,ber and London. Definition of global field Rings of integers of number fields Discriminants Quadratic fields.

V3 Cubic and sextic fields. Page 1 – We begin by considering the classical problem of when the prime number p can be represented as the sum of the squares of two integers.
II2 Valuations and absolute values. Zhang’s course on class field theory. III3 Nonramified and tamely ramified extensions. Here are some notes on local fields. It’s a theorem, or something, that everything written by Serre is beautiful. Cambridge University Press Amazon. A number of special topics are included that can be treated at this level but can usually only be found in research monographs or original papers, for instance: In the spring semester I organized meetings to answer questions and lecture on the background for Prof.
Account Options Sign in. Popular passages Page xiii – C denote the natural numbers, the integers, the rational numbers, the real numbers, the complex numbers respectively.
VIII6 Quadratic fields yet again. Ramification in local fields The p-adic exponential and logarithm Brief introduction to global fields. Characters of Finite Abelian Groups. This book is a nice introduction to, well, number fields. It even contains what is essentially the 1-dimensional case of Arakelov Theory. Read, highlight, and take notes, across web, tablet, and phone.
Introduction to Algebraic Number Theory
Very nice and complete introduction to Tate’s Thesis, and to the adelic approach to number theory in general.
III4 Ramification in Galois extensions. The treatment of class field theory, known as “Abstract Class Field Theory”, is due to Neukirch himself. Perhaps it’s a better resource for class field theory.
