Tropical dynamics of area-preserving maps

Abstract Full Text(HTML) Figure(13) Related Papers Cited by
  • We consider a class of area-preserving, piecewise affine maps on the 2-sphere. These maps encode degenerating families of K3 surface automorphisms and are profitably studied using techniques from tropical and Berkovich geometries.

Right: The dual subdivision of the Newton polytope. The Legendre transform of the function on the left determines the subdivision on the right. In the picture, all affine linear functions in the definition of $ h $ are minimized for some value of $ e_1, e_2 $

The domain is divided into $4$ triangles where the embedding is affine, with corresponding affine maps to $\mathbb{R}^3$ indicated on each triangle. The face and equations of the image tetrahedron are:
    $ABC: x+y-z+1 = 0 \quad \quad BCD: -(x+y+z) + 1 = 0$
    $ABD: x-y+z+1 = 0 \quad \quad ACD: -x+y+z + 1 = 0$
