Wonder what happened there. Hendrik Lenstra has some nice notes on the Galois Theory of Schemes ( websites.math.leidenuniv.nl/algebra/GSchemes.pdf ), which is a good place to find some of this material. It does give a nice exposure to algebraic geometry, though disclaimer I've never studied "real" algebraic geometry.

So you can take what I have to say with a grain of salt if you like. proof that abelian schemes assemble into an algebraic stack (Mumford. Volume 60, Number 1 (1954), 1-19. 0.4. Literally after phase 1, assuming you've grasped it very well, you could probably read Fulton's Algebraic Curves, a popular first-exposure to algebraic geometry. After thinking about these questions, I've realized that I don't need a full roadmap for now. theoretical prerequisite material) are somewhat more voluminous than for analysis, no? Complex analysis is helpful too but again, you just need some intuition behind it all rather than to fully immerse yourself into all these analytic techniques and ideas. And in some sense, algebraic geometry is the art of fixing up all the easy proofs in complex analysis so that they start to work again. As for things like étale cohomology, the advice I have seen is that it is best to treat things like that as a black box (like the Lefschetz fixed point theorem and the various comparison theorems) and to learn the foundations later since otherwise one could really spend way too long on details and never get a sense of what the point is. Note that I haven't really said what type of function I'm talking about, haven't specified the domain etc. Does it require much commutative algebra or higher level geometry? ), and provided motivation through the example of vector bundles on a space, though it doesn't go that deep: compactifications of the stack of abelian schemes (Faltings-Chai, Algebraic geometry ("The Maryland Lectures", in English), MR0150140, Fondements de la géométrie algébrique moderne (in French), MR0246883, The historical development of algebraic geometry (available. A masterpiece of exposition! You'll need as much analysis to understand some general big picture differential geometry/topology but I believe that a good calculus background will be more than enough to get, after phase 1, some introductory differential geometry ( Spivak or Do Carmo maybe? That Cox book might be a good idea if you are overwhelmed by the abstractness of it all after the first two phases but I dont know if its really necessary, wouldnt hurt definitely.. The books on phase 2 help with perspective but are not strictly prerequisites. I have only one recommendation: exercises, exercises, exercises! I am currently beginning a long-term project to teach myself the foundations of modern algebraic topology and higher category theory, starting with Lurie’s HTT and eventually moving to “Higher Algebra” and derived algebraic geometry. What is in some sense wrong with your list is that algebraic geometry includes things like the notion of a local ring. 6. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. You can jump into the abstract topic after Fulton and commutative algebra, Hartshorne is the classic standard but there are more books you can try, Görtz's, Liu's, Vakil's notes are good textbooks too! Or someone else will. One nice thing is that if I have a neighbourhood of a point in a smooth complex surface, and coordinate functions X,Y in a neighbourhood of a point, I can identify a neighbourhood of the point in my surface with a neighbourhood of a point in the (x,y) plane. I need to go at once so I'll just put a link here and add some comments later. For me, I think the key was that much of my learning algebraic geometry was aimed at applying it somewhere else. Is it really "Soon" though? One last question - at what point will I be able to study modern algebraic geometry? @DavidRoberts: thanks (although I am not 'mathematics2x2life', I care for those things) for pointing out. It makes the proof harder. the perspective on the representation theory of Cherednik algebras afforded by higher representation theory. Semi-algebraic Geometry: Background 2.1. Curves" by Arbarello, Cornalba, Griffiths, and Harris. These notes have excellent discussions of arithmetic schemes, Galois theory of schemes, the various flavors of Frobenius, flatness, various issues of inseparability and imperfection, as well as a very down to earth introduction to coherent cohomology. Articles by a bunch of people, most of them free online. You can certainly hop into it with your background. I disagree that analysis is necessary, you need the intuition behind it all if you want to understand basic topology and whatnot but you definitely dont need much of the standard techniques associated to analysis to have this intuition. All that being said, I have serious doubts about how motivated you'll be to read through it, cover to cover, when you're only interested in it so that you can have a certain context for reading Munkres and a book on complex analysis, which you only are interested in so you can read... Do you see where I'm going with this? And here, and throughout projective geometry, rational functions and meromorphic funcions are the same thing. A brilliant epitome of SGA 3 and Gabriel-Demazure is Sancho de Salas, Grupos algebraicos y teoria de invariantes. And now I wish I could edit my last comment, to respond to your edit: Kollar's book is great. Analysis represents a fairly basic mathematical vocabulary for talking about approximating objects by simpler objects, and you're going to absolutely need to learn it at some point if you want to continue on with your mathematical education, no matter where your interests take you. Algebraic Geometry, during Fall 2001 and Spring 2002. The first one, Ideals, Varieties and Algorithms, is undergrad, and talks about discriminants and resultants very classically in elimination theory. Title: Divide and Conquer Roadmap for Algebraic Sets. The main objects of study in algebraic geometry are systems of algebraic equa-tions and their sets of solutions. Here is the roadmap of the paper. Fulton's book is very nice and readable. GEOMETRYFROMPOLYNOMIALS 13 each of these inclusion signs represents an absolutely huge gap, and that this leads to the main characteristics of geometry in the different categories.
