Cox, Little, and O'Shea should be in Phase 1, it's nowhere near the level of rigor of even Phase 2. Also, in theory (though very conjectural) volume 2 of ACGH Geometry of Algebraic Curves, about moduli spaces and families of curves, is slated to print next year. Undergraduate roadmap to algebraic geometry? Articles by a bunch of people, most of them free online. 2) Fulton's "Toric Varieties" is also very nice and readable, and will give access to some nice examples (lots of beginners don't seem to know enough explicit examples to work with). Do you know where can I find these Mumford-Lang lecture notes? The book is sparse on examples, and it relies heavily on its exercises to get much out of it. This is where I have currently stopped planning, and need some help. I actually possess a preprint copy of ACGH vol II, and Joe Harris promised me that it would be published soon! Authors: Saugata Basu, Marie-Francoise Roy (Submitted on 14 May 2013 , last revised 8 Oct 2016 (this version, v6)) Abstract: Let $\mathrm{R}$ be a real closed field, and $\mathrm{D} \subset \mathrm{R}$ an ordered domain. It is this chapter that tries to demonstrate the elegance of geometric algebra, and how and where it replaces traditional methods. It is interesting, and indicative of how much knowledge is required in algebraic geometry, that Snapper recommends Weil's 'Foundations' at the … Volume 60, Number 1 (1954), 1-19. Th link at the end of the answer is the improved version. (2) RM 2For every x ∈ R and for every semi-algebraically connected component D of S I would appreciate if denizens of r/math, particularly the algebraic geometers, could help me set out a plan for study. Press question mark to learn the rest of the keyboard shortcuts. Ask an expert to explain a topic to you, the main ideas, that is, and the main theorems. The preliminary, highly recommended 'Red Book II' is online here. The first, and most important, is a set of resources I myself have found useful in understanding concepts. Although it’s not stressed very much in Hi r/math , I've been thinking of designing a program for self study as an undergraduate, with the eventual goal of being well-versed in. If it's just because you want to learn the "hardest" or "most esoteric" branch of math, I really encourage you to pick either a new goal or a new motivation. This is a pity, for the problems are intrinsically real and they involve varieties of low dimension and degree, so the inherent bad complexity of Gr¨obner bases is simply not an issue. at least, classical algebraic geometry. Note that I haven't really said what type of function I'm talking about, haven't specified the domain etc. real analytic geometry, and R[X] to algebraic geometry. proof that abelian schemes assemble into an algebraic stack (Mumford. And it can be an extremely isolating and boring subject. It explains the general theory of algebraic groups, and the general representation theory of reductive groups using modern language: schemes, fppf descent, etc., in only 400 quatro-sized pages! However, I feel it is necessary to precede the reproduction I give below of this 'roadmap' with a modern, cautionary remark, taken literally from http://math.stanford.edu/~conrad/: It is interesting, and indicative of how much knowledge is required in algebraic geometry, that Snapper recommends Weil's 'Foundations' at the end of this "How to get started"-section. Then there are complicated formalisms that allow this thinking to extend to cases where one is working over the integers or whatever. This page is split up into two sections. Is there something you're really curious about? I fear you're going to have a difficult time appreciating the subject if you make a mad dash through your reading list just so you can read what people are presently doing. ), and provided motivation through the example of vector bundles on a space, though it doesn't go that deep: Is there ultimately an "algebraic geometry sucks" phase for every aspiring algebraic geometer, as Harrison suggested on these forums for pure algebra, that only (enormous) persistence can overcome? 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. 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. Remove Hartshorne from your list and replace it by Shaferevich I, then Ravi Vakil. Modern algebraic geometry is as abstract as it is because the abstraction was necessary for dealing with more concrete problems within the field. 5) Algebraic groups. If you want to learn stacks, its important to read Knutson's algebraic spaces first (and later Laumon and Moret-Baily's Champs Algebriques). The approach adopted in this course makes plain the similarities between these different The tools in this specialty include techniques from analysis (for example, theta functions) and computational number theory. Unfortunately the typeset version link is broken. That's enough to keep you at work for a few years! So you can take what I have to say with a grain of salt if you like. Let R be a real closed field (for example, the field R of real numbers or R alg of real algebraic numbers). Once you've failed enough, go back to the expert, and ask for a reference. I'd add a book on commutative algebra instead (e.g. ALGORITHMIC SEMI-ALGEBRAIC GEOMETRY AND TOPOLOGY 3 2. There's a lot of "classical" stuff, and there's also a lot of cool "modern" stuff that relates to physics and to topology (e.g. Let V ⊂ C n be an equidimensional algebraic set and g be an n-variate polynomial with rational coefficients. I find both accessible and motivated. A week later or so, Steve reviewed these notes and made changes and corrections. With regards to commutative algebra, I had considered Atiyah and Eisenbud. Here is the roadmap of the paper. Even if I do not land up learning ANY algebraic geometry, at least we will created a thread that will probably benefit others at some stage. A masterpiece of exposition! It walks through the basics of algebraic curves in a way that a freshman could understand. 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? 4) Intersection Theory. For intersection theory, I second Fulton's book. Most people are motivated by concrete problems and curiosities. As you know, it says that under suitable conditions, given a real function f, there is a number x so that the average value of f is just f(x). 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. But he book is not exactly interesting for its theoretical merit, by which I mean there's not a result you're really going to come across that's going to blow your mind (who knows, maybe something like the Stone-Weirstrass theorem really will).
