An elementary proof of Sierksma's conjecture for seven points in the plane

Pablo Soberon · 2026

We give a new simple geometric proof that any seven points in the plane have four Tverberg partitions into three sets. This is the only confirmed non-trivial case of Sierksma's conjecture. Earlier pro…
