Parameterisation of a sphere

WebPseudo-Anosovs of interval type Ethan FARBER, Boston College (2024-04-17) A pseudo-Anosov (pA) is a homeomorphism of a compact connected surface S that, away from a finite set of points, acts locally as a linear map with one expanding and one contracting eigendirection. Ubiquitous yet mysterious, pAs have fascinated low-dimensional … Webgenus-0 mesh on the sphere. This relies on recent algebraic characterizations of convex embeddings due to Colin de Verdiere [1], and related eigenvector constructions due to Lovasz and Schrijver [6]. In practice it involves solving a set of quadratic equations.
