This masterly written text, now also available to the international mathematical audience, tells its own tale and represents a highly welcome addition to the great standard textbooks on algebraic geometry. I just wish they kept the original title, Why Schemes? Is it that EGA also covers a lot of commutative algebra, which you’d rather think of as a separate subject?

### Best Algebraic Geometry text book? (other than Hartshorne) – MathOverflow

Vishal rated it really liked it Feb 26, Sign up or log in Sign up using Google. Badescu – “Algebraic Surfaces”. These are the notes for a basic course in schemes and cohomology of sheaves. Note that the book that Arturo recommended is great also but it assumes you already know some algebraic geometry and its level is higher than Ueno’s book.

Ueno’s book is a self-contained introduction to this important circle of ideas, assuming only a knowledge of basic notions from abstract algebra such as prime ideals. This first volume gives a definition of schemes and describes some of their elementary properties. Shafarevich wrote a very basic introduction, it’s used in undergraduate classes in algebraic geometry sometimes Basic Algebraic Geometry 1: Shafarevich also has a Volume 2, on schemes and advanced topics.

It is not a short story of course, but again I prefer this type of approach at first, than having to deal with an heno and difficult definition that strives for great generality but I have no idea of where it comes from and what is its purpose.

Lazarsfeld – Positivity in Algebraic Geometry I: Also lots of things on jmilne.

The URL reference to the Gathmann lecture notes appears to be broken.

When I have to look up something in EGA, it’s like an infinite tree of theorems which I have to walk up. I’m really envious of the people who learn directly from the master Grothendieck.

## Algebraic Geometry

Algegraic it, you will certainly learn algebraic geometry. Yes, I think it is quite well-written and easy to proceed. The book begins with a description of the standard theory of algebraic varieties.

It’s also very well written, in my opinion. Liu wrote a nice book, which is a bit more oriented to arithmetic geometry. Beautifully written,comprehensive and not too abstract. At a lower level then Hartshorne is the fantastic “Algebraic Curves” by Fulton.

Arturo Magidin k 32 Besides, Mumford himself developed the subject. Is it the length? Grothendieck, Alexander The cohomology theory of abstract algebraic varieties. Then, sheaves are introduced and studied, using as few prerequisites as possible.

Out of curiosity, can you elaborate on what you like about this book? Alternatives are more introductory lectures by Dolgachev. The combined table of contents unfortunately seems to be defunct. It does a great job complementing Hartshorne’s aogebraic of schemes, above all because of the more solvable exercises. Every step seems to be trivial, yeah. For a down to earth introduction, Milne’s notes are nice but they don’t go to the scheme level, they give the taste of it.

Gathmann – “Algebraic Geometry” which can be found here.

## Algebraic Geometry 1: From Algebraic Varieties to Schemes

A sheaf is a way of keeping track of local information defined on a topological space, such as the local holomorphic f Algebraic geometry is built upon two fundamental notions: I only found the notes of previous years on the web. This was followed by another fundamental change in the s with Grothendieck’s introduction of schemes.

Obviously I’m taking liberties with the question, as I wouldn’t advertise Huybrechts’ kwnji as an algebraic geometry text in the strict sense. Libraries and resellers, please contact cust-serv ams.

### Algebraic Geometry by Kenji Ueno

Introduction to Algebraic Geometry. I must admit that I find it almost unreadable, owing to the old-fashioned geoetry.

Well, to be fair, this is only the first in geomerry series of three books on the subject by the same author. And then at the end of the first chapter the author motivates the need for a more general theory, for example having in mind the needs of number theory, because since everything was done in the context of an algebraically closed field, then the arguments don’t work for the fields and rings of interest in number theory.
