Planar posets have dimension at most linear in their height

Abstract

We prove that every planar poset PP of height hh has dimension at most 192h+96192h + 96. This improves on previous exponential bounds and is best possible up to a constant factor. We complement this result with a construction of planar posets of height hh and dimension at least (4/3)h2(4/3)h-2.
