Algebraic geometry - Wikipedia

In mathematics, specifically in algebraic geometry, a formal scheme is a type of space which includes data about its surroundings. Unlike an ordinary scheme, a formal scheme includes infinitesimal data that, in effect, points in a direction off of the scheme. For this reason, formal schemes frequently appear in topics such as deformation theory. But the concept is also used to prove a theorem such as the theorem on formal functions, which is used to deduce theorems of … WebALGEBRAIC AND FORMAL GEOMETRY 3 considerthemaps Hi(U,F) −→limHi(U,F/InF) andaskifwegetanisomorphisminacertainrangeofdegrees.

Giving a scheme is the same as giving the corresponding functor from the category of rings to the category of set, and there are characterization of what functors arise in this way.

WebThe formal neighbourhood of a closed subscheme X of Y refers to the formal scheme obtained by completing Y along X; see the discussion of formal schemes in Hartshorne for (unfortunately not that many) more details. This is certainly not an open subscheme of Y; indeed, as Marci notes, the underlying topological space is simply X itself.
