A remark on the paper "Properties of intersecting families of ordered sets" by O. Einstein
arXiv:1705.10947 · doi:10.1007/s00493-018-3812-3
Abstract
O. Einstein (2008) proved Bollobás-type theorems on intersecting families of ordered sets of finite sets and subspaces. Unfortunately, we report that the proof of a theorem on ordered sets of subspaces had a mistake. We prove two weaker variants.
