On automorphisms of blowups of P3

Tuyen Trung Truong

Abstract: Let pi : X -> P^3 be a finite composition of blowups along smooth centers. We show that for "almost all" of such X, if f is in Aut(X) then its first and second dynamical degrees are the same. We also construct many examples of finite blowups X -> P^3 every automorphism of which has zero topological entropy.
