Covering large balls with convex sets in spherical spaceKároly Bezdek and Rolf SchneiderDepartment of Mathematics and Statistics, University of Calgary, 2500 University Drive N.W., AB, Canada, T2N 1N4, e-mail: bezdek@math.ucalgary.ca; Mathematisches Institut, Albert-Ludwigs-Universität, Eckerstr. 1, D-79104 Freiburg i. Br., Germany, e-mail: rolf.schneider@math.uni-freiburg.deAbstract: If the $n$-dimensional unit sphere is covered by finitely many spherically convex bodies, then the sum of the inradii of these bodies is at least $\pi$. This bound is sharp, and the equality case is characterized. Keywords: spherical coverings, plank problem, spherical volume, inradius Classification (MSC2000): 52A55, 52C17 Full text of the article:
