On a transversal theorem of Montejano and Karasev

Combinatorics 2024-09-06 v2

Abstract

We give a new proof of a theorem of Montejano and Karasev regarding kk-dimensional transversals to small families of convex sets. While their proof uses technical algebraic and topological tools, our proof is a simple application of the Borsuk-Ulam theorem. Additionally, in certain cases our result is stronger than the Montejano-Karasev theorem.
