Orbifold splice quotients and log covers of surface pairs
Walter D. Neumann, Jonathan Wahl
A three-dimensional orbifold , where is a rational homology sphere, has a universal abelian orbifold covering, whose covering group is the first orbifold homolog…
Non-isomorphism of categories of algebras
Walter D Neumann
This paper was accepted for Comment. Math. Univ. Carolinae in 1968 but then got lost during the military occupation of Prague and surrounding events. My own long-lost carbon copy o…
A characterization of Lipschitz normally embedded surface singularities
Walter D Neumann, Helge Møller Pedersen, Anne Pichon
Any germ of a complex analytic space is equipped with two natural metrics: the outer metric induced by the hermitian metric of the ambient space and the inner metric, which is the…
Topology of hypersurface singularities
Walter D Neumann
Kähler's paper "Über die Verzweigung einer algebraischen Funktion zweier Veränderlichen in der Umgebung einer singulären Stelle" offered a more perceptual view of the link of a com…
Lipschitz geometry does not determine embedded topological type
Walter D. Neumann, Anne Pichon
We investigate the relationships between the Lipschitz outer geometry and the embedded topological type of a hypersurface germ in . It is well known that the Lipsc…
Minimal surface singularities are Lipschitz normally embedded
Walter D Neumann, Helge Møller Pedersen, Anne Pichon
Any germ of a complex analytic space is equipped with two natural metrics: the {\it outer metric} induced by the hermitian metric of the ambient space and the {\it inner metric}, w…
