A cusp singularity with no Galois cover by a complete intersection

David E. Anderson

Published 2001-09-18, updated 2002-07-16Version 3

With an explicit example, we confirm a conjecture by Neumann and Wahl that there exist cusps with no Galois cover by a complete intersection. Some computational techniques are reviewed, and a method for deciding whether a given cusp has a complete intersection Galois cover is developed.
