The Topology of the set of line Transversals
Published 29 May 2022 in math.MG | (2205.14681v2)
Abstract: We prove that for any set $F$ of $n\ge 2$ pairwise disjoint open convex sets in $\mathbb{R}3$, the connected components of the set of lines intersecting every member of $F$ are contractible. The same result holds for directed lines.
