Thanks! This is is, of course, an enormous topic, but I think it’s an exciting application of the theory, and one worth discussing a bit. To try to explain my sense, looking at this list of books, it reminds me of, say, a calculus student wanting to learn the mean value theorem. 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.. Well you could really just get your abstract algebra courses out of the way, so you learn what a module is. 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? I anticipate that will be Lecture 10. Then they remove the hypothesis that the derivative is continuous, and still prove that there is a number x so that g'(x) = (g(b)-g(a))/(b-a). The approach adopted in this course makes plain the similarities between these different But now the intuition is lost, and the conceptual development is all wrong, it becomes something to memorize. The following seems very relevant to the OP from a historical point of view: a pre-Tohoku roadmap to algebraic topology, presenting itself as a "How to" for "most people", written by someone who thought deeply about classical mathematics as a whole. My advice: spend a lot of time going to seminars (and conferences/workshops, if possible) and reading papers. There are a lot of cool application of algebraic spaces too, like Artin's contraction theorem or the theory of Moishezon spaces, that you can learn along the way (Knutson's book mentions a bunch of applications but doesn't pursue them, mostly sticks to EGA style theorems). The first two together form an introduction to (or survey of) Grothendieck's EGA. (/u/tactics), Fulton's Algebraic Curves for an early taste of classical algebraic geometry (/u/F-0X), Commutative Algebra with Atiyah-MacDonald or Eisenbud's book (/u/ninguem), Category Theory (not sure of the text just yet - perhaps the first few captures of Mac Lane's standard introductory treatment), Complex Analysis (/u/GenericMadScientist), Riemann Surfaces (/u/GenericMadScientist), Algebraic Geometry by Hartshorne (/u/ninguem). When you add two such functions, the domain of definition is taken to be the intersection of the domains of definition of the summands, etc. A semi-algebraic subset of Rkis a set defined by a finite system of polynomial equalities and I dont like Hartshorne's exposition of classical AG, its not bad its just short and not helpful if its your first dive into the topic. Algebraic Geometry seemed like a good bet given its vastness and diversity. This includes, books, papers, notes, slides, problem sets, etc. A brilliant epitome of SGA 3 and Gabriel-Demazure is Sancho de Salas, Grupos algebraicos y teoria de invariantes. Most people are motivated by concrete problems and curiosities. It walks through the basics of algebraic curves in a way that a freshman could understand. But learn it as part of an organic whole and not just rushing through a list of prerequisites to hit the most advanced aspects of it. Same here, incidentally. Curves" by Arbarello, Cornalba, Griffiths, and Harris. I have owned a prepub copy of ACGH vol.2 since 1979. Yes, it's a slightly better theorem. Oh yes, I totally forgot about it in my post. For me, I think the key was that much of my learning algebraic geometry was aimed at applying it somewhere else. Atiyah-MacDonald).

The rest is a more general list of essays, articles, comments, videos, and questions that are interesting and useful to consider. It's much easier to proceed as follows. It can be considered to be the ring of convergent power series in two variables. So, many things about the two rings, the one which is a localized polynomial algebra and the one which is not quite, are very similar to each other. 1) I'm a big fan of Mumford's "Curves on an algebraic surface" as a "second" book in algebraic geometry. MathOverflow is a question and answer site for professional mathematicians. Is there a specific problem or set of ideas you like playing around with and think the tools from algebraic geometry will provide a new context for thinking about them? Algebraic geometry is a branch of mathematics, classically studying zeros of multivariate polynomials.Modern algebraic geometry is based on the use of abstract algebraic techniques, mainly from commutative algebra, for solving geometrical problems about these sets of zeros.. Here's my thought seeing this list: there is in some sense a lot of repetition, but what will be hard and painful repetition, where the same basic idea is treated in two nearly compatible, but not quite comipatible, treatments. Right now, I'm trying to feel my way in the dark for topics that might interest me, that much I admit. We shall often identify it with the subset S. After thinking about these questions, I've realized that I don't need a full roadmap for now. algebraic geometry regular (polynomial) functions algebraic varieties topology continuous functions topological spaces differential topology differentiable functions differentiable manifolds complex analysis analytic (power series) functions complex manifolds. Open the reference at the page of the most important theorem, and start reading. Thank you, your suggestions are really helpful. 0.4. Or are you just interested in some sort of intellectual achievement? This page is split up into two sections. Springer's been claiming the earliest possible release date and then pushing it back. computational algebraic geometry are not yet widely used in nonlinear computational geometry. I … Of course it has evolved some since then. From whom you heard about this? 3) More stuff about algebraic curves. A roadmap for a semi-algebraic set S is a curve which has a non-empty and connected intersection with all connected components of S. More precisely, let V and W be […] It is a good book for its plentiful exercises, and inclusion of commutative algebra as/when it's needed. The best book here would be "Geometry of Algebraic That's enough to keep you at work for a few years! I too hate broken links and try to keep things up to date. I would suggest adding in Garrity et al's excellent introductory problem book, Algebraic Geometry: A Problem-solving Approach. But now, if I take a point in a complex algebraic surface, the local ring at that point is not isomorphic to the localized polynomial algebra. at least, classical algebraic geometry. Wow,Thomas-this looks terrific.I guess Lang passed away before it could be completed? The first, and most important, is a set of resources I myself have found useful in understanding concepts. Keep diligent notes of the conversations. I'm a big fan of Springer's book here, though it is written in the language of varieties instead of schemes.
