Vertex decomposable 3-ball with a knotted spanning arc

www.eg-models.de

Electronic Geometry Model No Author. Nikolaus Witte. Description. Hachimori and Ziegler [1] proved that a triangulation of a 3-ball which contains a knotted spanning arc consisting of at most 3 edges is not vertex decomposable. The following example (constructed along the ideas of Hachimori and Ziegler [1], ...
