Title: Weighted homogeneous singularities and rational
homology disk smoothings

Abstract: We classify the resolution graphs of weighted homogeneous surface
singularities which admit rational homology disk smoothings. The
nonexistence of rational homology disk smoothings is shown by
symplectic geometric methods, while the existence is verified via
smoothings of negative weight.
