Illumination and visibility problems in terms of closure operatorsHorst Martini and Walter WenzelFaculty of Mathematics, University of Technology Chemnitz, D--09107 Chemnitz, GermanyAbstract: 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 Classification (MSC2000): 52A20; 52A01, 52A37 Full text of the article:
