With respect to my background, I have knowledge of the basics of algebraic geometry, scheme theory, smooth manifolds, affine connections and other stuff. Try to prove the theorems in your notes or find a toy analogue that exhibits some of the main ideas of the theory and try to prove the main theorems there; you'll fail terribly, most likely. What do you even know about the subject? 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. Most people are motivated by concrete problems and curiosities. An inspiring choice here would be "Moduli of Curves" by Harris and Morrison. construction of the dual abelian scheme (Faltings-Chai, Degeneration of abelian varieties, Chapter 1). 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? 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). real analytic geometry, and R[X] to algebraic geometry. We shall often identify it with the subset S. 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. Note that I haven't really said what type of function I'm talking about, haven't specified the domain etc. (/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). 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. It makes the proof harder. I am sure all of these are available online, but maybe not so easy to find. I would appreciate if denizens of r/math, particularly the algebraic geometers, could help me set out a plan for study. Is there something you're really curious about? I highly doubt this will be enough to motivate you through the hundreds of hours of reading you have set out there. Right now, I'm trying to feel my way in the dark for topics that might interest me, that much I admit. Then there are complicated formalisms that allow this thinking to extend to cases where one is working over the integers or whatever. The nice model of where everything works perfectly is complex projective varieties, and meromorphic functions. Semi-algebraic Geometry: Background 2.1. I like the use of toy analogues. 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. Which phase should it be placed in? site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. It only takes a minute to sign up. 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 process for producing this manuscript was the following: I (Jean Gallier) took notes and transcribed them in LATEX at the end of every week. computational algebraic geometry are not yet widely used in nonlinear computational geometry. I'm interested in learning modern Grothendieck-style algebraic geometry in depth. The best book here would be "Geometry of Algebraic The main objects of study in algebraic geometry are systems of algebraic equa-tions and their sets of solutions. I'll probably have to eventually, but I at least have a feel for what's going on without having done so, and other people have written good high-level expositions of most of the stuff that Grothendieck did. In all these facets of algebraic geometry, the main focus is the interplay between the geometry and the algebra. Gromov-Witten theory, derived algebraic geometry). Some of this material was adapted by Eisenbud and Harris, including a nice discussion of the functor of points and moduli, but there is much more in the Mumford-Lang notes." 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. 0.4. BY now I believe it is actually (almost) shipping. Is it really "Soon" though? AG is a very large field, so look around and see what's out there in terms of current research. A brilliant epitome of SGA 3 and Gabriel-Demazure is Sancho de Salas, Grupos algebraicos y teoria de invariantes. I'm only an "algebraic geometry enthusiast", so my advice should probably be taken with a grain of salt. This makes a ring which happens to satisfy all the nice properties that one has in algebraic geometry, it is Noetherian, it has unique factorization, etc. Cox, Little, and O'Shea should be in Phase 1, it's nowhere near the level of rigor of even Phase 2.
