Bi-Lipschitz geometry of weighted homogeneous surface singularities
Lev Birbrair, Alexandre Fernandes, Walter D. Neumann
We show that a weighted homogeneous complex surface singularity is metrically conical (i.e., bi-Lipschitz equivalent to a metric cone) only if its two lowest weights are equal. We…

Walter D Neumann
We give a very short proof that a subgroup of a free group that is positively generated cannot be part of a counterexample to the Generalized Hanna Neumann Conjecture.
