A number field K is a finite algebraic extension of the rational numbers Q. Every such extension can be represented as all polynomials in an algebraic number α: K = Q(α) = (Xm n=0 anα n: a n ∈ Q). Here α is a root of a polynomial with coefficients in Q.

Cassels and Fröhlich. First printed in , this book has been essential reading for aspiring algebraic number theorists for more than. Solutions to the Cassels-Fröhlich exercises. Dorian Ni. May First of all, many thanks to Kevin Buzzard for his kind help, and for his willingness to answer . Cassels–Froehlich errata. July 18, Consider what God has done: Who can straighten what he has made crooked? Ecclesiastes 1 These errata.

Algebraic Number Theory PROCEEDINGS OF AN INSTRUCTIONAL CONFERENCE ORGANIZED BY THE LONDON MATHEMATICAL SOCIETY (A NATO ADVANCED STUDY INSTITUTE) WITH THE SUPPORT OF THE INTERNATIONAL MATHEMATICAL UNION Edited by J. CASSELS Trinity College, University of Cambridge, U.K. FRiiHLICH King’s University of London, ACADEMIC PRESS. CF Cassels and Frohlich, Algebraic Number Theory. Uses local fields and adeles heavily. The basics are covered very quickly, however. Perhaps it's a better resource for class field theory. This is where original Tate's Thesis was published (though 17 years after it was written.) Neukirch Neukirch, Algebraic Number Theory.

The Theorem in the latter section is the correct formulation: Page 54, line The Brauer argument below makes acssels all moot. Frohlivh think the “action” they define is not an action, and I think the first couple of sentences of section 4 should be:. I posted this question in several other places as well the nmbrthry mailing list, and sci. I happened to notice these misprints this morning: Sign up using Email and Password. I’ve started reading chapter 1. In my opinion this is an excellent example of a good community wiki question!

The right-hand caesels should be the reciprocal of what it is in the book.

Also, the verification that the displayed map is actually inverse to the Artin map seems to merit a tiny bit of explanation using the identification of artin map with cup product against fundamental class in Serre’s treatment frohljch the local case.

This Proposition is misstated, and the proof has the wrong reference: Page 75, line 1: But judging by the upvotes I have misjudged this. Bill Stein independently got in touch with me to tell me about the two typos on p99 he’s giving a talk on that chapter in 30 minutes’ time!

Email Required, but never shown. Edit 25 April I clearly misjudged thisthe question has a good few upvotes now.

And here’s one which I spotted: Thanks to everyone who helped. The London Mathematical Society would like to know all the errors I’ve made myself, by 12th of February, so feel free to let me know of anything, however trivial! Pageline Pagelast line before Corollary 1: This is what I scrawled, I frolhich not verify it at the present occasion!

Does anyone else have any scrawled marginal notes in their copies of Cassels-Froehlich about typos or other things that the LMS can fix?

I have a physical copy of the new printing of the book. Pageline 14 the first display: The notation frlhlich also terrible: Pageline 4: If this definition is used then what the authors write seems to be OK.

Page 78, line -8 display A. Here’s one I didn’t see on the list on mathoverflow: I agree, this seems like an excellent question.

I think I just found a typo in the definition of a co-induced module on p Casaels did not do any proofreading of my list either!! More or less coincidentally, the Proposition is correct as stated exercise! MathOverflow works best with JavaScript enabled.

Ok so it looks like I misjudged this and the community seem happy to have the question here, at least at present. In my copy of the book, the footnote does not refer to Stalin. Pageline 2 after the diagram: Page 52, part 3 of the first definition: Sign up using Facebook.

It’s “borderline when it comes to what I want MO frohlichh be” ;- which is just loads of fun precisely-worded questions with precise answers. Thanks to everyone that contributed. Pagefirst line after Definition:

Discussion on this thread is happening here at the meta. Pageline 1: Pageline 3: They are planning on having an erratum page at the beginning of the book when they reprint it.

I think the “action” they define is not an action, and I think the first couple of sentences of section 4 should be: In fact, especially in its modern cohomological formulation, it is much more, serving as a bridge between the classical algebraic number theory of the 19th alggebraic Kronecker-Weber theorem, etc.

Anton and Ilya have suggested that really this would be better if it had one big answer rather than lots of smaller ones. That’s a lot, but the semester is long. This is a course on local and global class field theory, and applications as time permits.
