A finite partially ordered set (poset) P is customarily represented by drawing a small circle for each point, with a lower than b whenever a < b in P, and drawing a straight line segment from a to b whenever a is covered by b in P (see, for example, G. Birkhoff [2, p. 4]). A poset P is planar if such a diagram can be drawn for P in which none of the

Recent developments in planar electrochromatography (PEC) in both the normal-phase and the reversed-phase modes, and at both atmospheric and elevated pressure, are reviewed. Other forced-flow techniques in planar chromatography are also briefly covered.

On boolean characterizations of planarity and planar embeddings of graphs
Annals of Operations Research, 1990The author introduces a new planarity characterization for graphs, involving the solution of a quadratic Boolean equation. He then discusses seven combinatorially distinct configurations, called planarity obstacles, which lead to a graph whose order and size are linear functions of those of the original graph. Testing for planarity and finding a planar
