Colourful transversal theorems
Déborah Oliveros, Luis Pedro Montejano · Libraries and Cultural Resources (University of Calgary) · 2007
We prove the colourful versions of three clasical transversal theorems: The Katchalski-Lewis Theorem "T(3) implies T-k", the "T(3) implies T" Theorem for well distributed sets, and the Goodmann-Pollack Transversal Theorem for hyperplanes.
