2	Intersection of valuation rings in k[x, y] Junyi Xie IRMAR, CNRS Arithmetic Geometry and Commutative Algebra mathscidoc:1908.07001 Proc. London Math. Soc. , 2015 [ Download ] [ 2019-08-21 18:20:52 uploaded by xiejunyi ] [ 875 downloads ] [ 0 comments ] Abstract × We associate to any given finite set of valuations on the polynomial ring in two variables over an algebraically closed field a numerical invariant whose positivity characterizes the case when the intersection of their valuation rings has maximal transcendence degree over the base fields. As an application, we give a criterion for when an analytic branch at infinity in the affine plane that is defined over a number field in a suitable sense is the branch of an algebraic curve.

4	Algebraic actions of discrete groups: the p-adic method Serge Cantat IRMAR,CNRS Junyi Xie IRMAR,CNRS Dynamical Systems mathscidoc:1908.01002 Silver Award Paper in 2020 Acta Mathematica, 220, (2), 239 – 295, 2018 [ Download ] [ 2019-08-21 18:28:11 uploaded by xiejunyi ] [ 1066 downloads ] [ 0 comments ] Abstract × We study groups of automorphisms and birational transformations of quasi-projective varieties. Two methods are combined; the first one is based on p-adic analysis, the second makes use of isoperimetric inequalities and Lang–Weil estimates. For instance, we show that, if SLn(Z) acts faithfully on a complex quasi-projective variety X by birational transformations, then dim(X)⩾n−1 and X is rational if dim(X)=n−1.
