Abstract: | This paper describes relations between convex polytopes and certain families of convex cones in R
n
.The purpose is to use known properties of convex cones in order to solve Helly type problems for convex sets in R
n
or for spherically convex sets in S
n
, the n-dimensional unit sphere. These results are strongly related to Gale diagrams. |
