A better description of algebraic geometry is that it is the study of polynomial functions and the spaces on which they are defined (algebraic varieties), just as topology is the study of continuous functions and the spaces on which they are defined (topological spaces),
essential differences between algebraic geometry and the other fields, the inverse function theorem doesn’t hold in algebraic geometry One other essential difference is that 1=Xis not the derivative of any rational function of X, and nor is X np1 in characteristic p¤0 — these functions can not be integrated in the ring of polynomial
The classical objects of study in algebraic geometry is an algebraic variety (on the other hand, the work-ing algebraic geometer doesn’t often think about these) over a eld k Roughly, algebraic varieties are the set of solutions to a system of polynomial equations with coe cients in k
A note about figures In algebraic geometry, the dimensions are too big to allow realistic figures Even with an affine plane curve, one is dealing with a locus in the space A2, whose dimension in the classical topology is four In some cases, such as in Figure 1 1 2 above, depicting the real locus can be helpful, but in most cases,

to algebraic geometry Although some of the exposition can be followed with only a minimum background in algebraic geometry, for example, based on Shafarevich’s book [531], it often relies on current cohomological techniques, such as those found in Hartshorne’s book [283] The idea was to reconstruct

Transcendental methods of algebraic geometry have been extensively studied since a long time, starting with the work of Abel, Jacobi and Riemann in the nineteenth century More recently, in the period 1940-1970, the work of Hodge, Hirzebruch, Kodaira, Atiyah revealed deeper relations between complex analysis, topology, PDE theory and algebraic geometry In the last twenty years, gauge theory has
