Finite Coverings and Rational Points
نویسنده
چکیده
The purpose of this talk is to put forward a conjecture. The background is given by the following Basic Question. Given a (smooth projective) curve C over a number field k, can we determine explicitly the set C(k) of rational points? One possible approach to this is to consider an unramified covering D π → C that is geometrically Galois. By standard theory, there are only finitely many twists Dj πj → C of this covering (up to isomorphism over k) such that Dj has points everywhere locally, and C(k) = ∐

The Thurston Type Theorem for Branched Coverings of Two-Sphere
I give a survey about a program which intends to find topological characterizations of a rational map and then use them to study the rigidity problem for rational maps. Thurston started this program by considering critically finite branched coverings and gave a necessary and sufficient combinatorial condition for a critically finite rational maps among all critically finite branched coverings. ...
متن کاملALGEBRAS WITH CYCLE-FINITE STRONGLY SIMPLY CONNECTED GALOIS COVERINGS
Let $A$ be a nite dimensional $k-$algebra and $R$ be a locally bounded category such that $R rightarrow R/G = A$ is a Galois covering dened by the action of a torsion-free group of automorphisms of $R$. Following [30], we provide criteria on the convex subcategories of a strongly simply connected category R in order to be a cycle- nite category and describe the module category of $A$. We p...
متن کاملCombinatorial characterization of sub-hyperbolic rational maps
In 1980’s, Thurston established a combinatorial characterization for post-critically finite rational maps among post-critically finite branched coverings of the two sphere to itself. A completed proof was written by Douady and Hubbard in their paper [A. Douady, J.H. Hubbard, A proof of Thurston’s topological characterization of rational functions, Acta Math. 171 (1993) 263–297]. This criterion ...
