Abstract

Huybrechts proved that a stability condition on a K3 surface is determined by the stability of spherical objects. Motivated by the study of the Thurston compactification of spaces of stability conditions expected by Bapat, Deopurlar and Licata, I would like to show that a stability condition on a K3 surface is determined by the mass of spherical objects. This talk is based on the joint work with Kohei Kikuta and Naoki Koseki.

Geometric decompositions of spherical surfaces
AbstractIt is well-known that any plane polygon can be decomposed along its diagonals into flat triangles. The analog does not hold for spherical polygons. We prove that any compact surface with constant positive curvature and conical singularities can be decomposed into irreducible components of standard shape, glued along geodesic arcs connecting conical singularities. The irreducible compone...
