Lower Semi-Continuity of Entropy in a Family of K3 Surface Automorphisms

Lower Semi-Continuity of Entropy in a Family of K3 Surface Automorphisms

We compute entropies in a large family of K3 surface automorphisms in (P^1)^3. In keeping with a result by Xie, we find that the entropies vary in a lower semi-continuous manner as the Picard ranks of the K3 surfaces vary.
