The 2-generalized knot group determines the knot

Sam Nelson, Walter D. Neumann

Generalized knot groups $G_{n} (K)$ were introduced independently by Kelly (1991) and Wada (1992). We prove that $G_{2} (K)$ determines the unoriented knot type and sketch a proof of the…

Bi-Lipschitz geometry of complex surface singularities

Lev Birbrair, Alexandre Fernandes, Walter D. Neumann

We discuss the bi-Lipschitz geometry of an isolated singular point of a complex surface which particular emphasis on when it is metrically conical.
