Yu-Wei Fan, Simion Filip
We introduce invariants, called shifting numbers, that measure the asymptotic amount by which an autoequivalence of a triangulated category translates inside the category. The inva…

Tropical Dynamics of Area-Preserving Maps
Simion Filip
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…
