Polygons with Hidden Vertices
Fakultät und Institut für Mathematik, Ruhr-Universität Bochum, Universitätsstrasse 150, D-44801 Bochum, Germany
Abstract: Given a point $M$ in Euclidean 3-space we show that there exists a polygon without self-intersection and not containing $M$ such that viewed from $M$ each vertex of the polygon is hidden behind an edge of the polygon. As an application, we construct a toric 4-variety which has peculiar compactification properties.
