Also, to what degree would it help to know some analysis? To learn more, see our tips on writing great answers. And we say that two functions are considered equal if they both agree when restricted to some possibly smaller neighbourhood of (0,0) -- that is, the choice of neighbourhood of definition is not part of the 'definition' of our functions. So, does anyone have any suggestions on how to tackle such a broad subject, references to read (including motivation, preferably! A masterpiece of exposition! Asking for help, clarification, or responding to other answers. A learning roadmap for algebraic geometry, staff.science.uu.nl/~oort0109/AG-Philly7-XI-11.pdf, staff.science.uu.nl/~oort0109/AGRoots-final.pdf, http://www.cgtp.duke.edu/~drm/PCMI2001/fantechi-stacks.pdf, http://www.math.uzh.ch/index.php?pr_vo_det&key1=1287&key2=580&no_cache=1, thought deeply about classical mathematics as a whole, Equivalence relations in algebraic geometry, in this thread, which is the more fitting one for Emerton's notes. Is complex analysis or measure theory strictly necessary to do and/or appreciate algebraic geometry? 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 regular (polynomial) functions algebraic varieties topology continuous functions topological spaces differential topology differentiable functions differentiable manifolds complex analysis analytic (power series) functions complex manifolds. Reading tons of theory is really not effective for most people. In algebraic geometry, one considers the smaller ring, not the ring of convergent power series, but just the polynomials. 6. It covers conics, elliptic curves, Bezout's theorem, Riemann Roch and introduces the basic language of algebraic geometry, ending with a chapter on sheaves and cohomology. ), or advice on which order the material should ultimately be learned--including the prerequisites? EDIT : I forgot to mention Kollar's book on resolutions of singularities. Articles by a bunch of people, most of them free online. Use MathJax to format equations. At LSU, topologists study a variety of topics such as spaces from algebraic geometry, topological semigroups and ties with mathematical physics. 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). Unfortunately I saw no scan on the web. @DavidRoberts: thanks (although I am not 'mathematics2x2life', I care for those things) for pointing out. I … 0.4. More precisely, let V and W be […] 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. I learned a lot from it, and haven't even gotten to the general case, curves and surface resolution are rich enough. I highly doubt this will be enough to motivate you through the hundreds of hours of reading you have set out there. Making statements based on opinion; back them up with references or personal experience. This has been wonderfully typeset by Daniel Miller at Cornell. It's more a terse exposition of terminology frequently used in analysis and some common results and techniques involving these terms used by people who call themselves analysts. There is a negligible little distortion of the isomorphism type. The first one, Ideals, Varieties and Algorithms, is undergrad, and talks about discriminants and resultants very classically in elimination theory. For a small sample of topics (concrete descent, group schemes, algebraic spaces and bunch of other odd ones) somewhere in between SGA and EGA (in both style and subject), I definitely found the book 'Néron Models' by Bosch, Lütkebohmert and Raynaud a nice read, with lots and lots of references too. rev 2020.12.18.38240, The best answers are voted up and rise to the top, MathOverflow works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. To be honest, I'm not entirely sure I know what my motivations are, if indeed they are easily uncovered. It's much easier to proceed as follows. Ask an expert to explain a topic to you, the main ideas, that is, and the main theorems. Modern algebraic geometry is as abstract as it is because the abstraction was necessary for dealing with more concrete problems within the field. I have some familiarity with classical varieties, schemes, and sheaf cohomology (via Hartshorne and a fair portion of EGA I) but would like to get into some of the fancy modern things like stacks, étale cohomology, intersection theory, moduli spaces, etc. I would appreciate if denizens of r/math, particularly the algebraic geometers, could help me set out a plan for study. Section 1 contains a summary of basic terms from complex algebraic geometry: main invariants of algebraic varieties, classi cation schemes, and examples most relevant to arithmetic in dimension 2. You could get into classical algebraic geometry way earlier than this. 4) Intersection Theory. 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. One thing is, the (X,Y) plane is just the projective plane with a line deleted, and polynomials are just rational functions which are allowed to have poles on that line. 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. It does give a nice exposure to algebraic geometry, though disclaimer I've never studied "real" algebraic geometry. 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. 3 Canny's Roadmap Algorithm . I think that people allow themselves to be vague sometimes: when you say 'closed set' do you mean defined by polynomial equations, or continuous equations, or analytic equations?
