Anabelian geometry
Anabel's geometry is a mathematical research program by Alexander Grothendieck on the étale fundamental group in algebraic geometry .
More precisely, it is assumed of certain categories of schemes that the functor has an exact left adjoint for them.
An example of such a category is that of the module spaces of curves. The conjecture was proven in 1994 for this case by Florian Pop .
