| Universal abelian covers of quotient-cusps (2001) | |||||||||
Abstract | |||||||||
| The quotient-cusp singularities are isolated complex surface singularities that are double-covered by cusp singularities. We show that the universal abelian cover of such a singularity, branched only at the singular point, is a complete intersection cusp singularity of embedding dimension 4. This supports a general conjecture that we make about the universal abelian cover of a $\Q$-Gorenstein singularity.. Comment: 16 pages | |||||||||
