Integral-affine Structures and Degenerations of K3 Surfaces
Philip Engel (University of Georgia)
Abstract
I will discuss a correspondence between degenerations of polarized K3 surfaces and integral-affine structures on the 2-sphere containing a weighted balanced graph. Under this correspondence, natural questions emerge about the dynamics of the straight line flow on integral-affine manifolds. We will explore (1) the relationship between closed trajectories and immersed elliptic curves in the K3 surface, and (2) the possibility of a tropical Yau-Zaslow formula for counting immersed trees.
