| Rational Trees |
| Abstract: A normal surface singularity is rational if and only if the dual graph of a desingularization satisfies some combinatorial properties. In fact, these graphs are trees. In this paper we give geometric features of these trees. In particular, we prove that the number of vertices of valency >= 3 in the dual tree of the minimal desingularization of a rational singularity of multiplicity m >= 3 is at most m-2. |
