摘要：With Serge Cantat, we study groups of automorphisms and birational transformations of quasi-projective varieties by p-adic methods. For instance, we show that if SL(n,Z) acts faithfully on a complex quasi-projective variety X by birational transformations, then dim(X) is at least n-1 and if it equals to n-1, then X is rational.
