Illumination and visibility problems in terms of closure operators
Horst Martini and Walter WenzelFaculty of Mathematics, University of Technology Chemnitz, D--09107 Chemnitz, Germany
Abstract: The notions of illumination and visibility of convex bodies are well-known in combinatorial and computational geometry. We study closure operators which control illumination and visibility, respectively.
Keywords: convex bodies, illumination, visibility, closure operators, Hadwiger's covering problem
