A Separator Theorem for Planar Graphs
, 1977
"... Let G be any nvertex planar graph. We prove that the vertices of G can be partitioned into three sets A, B, C such that no edge joins a vertex in A with a vertex in B, neither A nor B contains more than 2n/3 vertices, and C contains no more than 2& & vertices. We exhibit an algorithm which ..."

Planar embedding of planar graphs
 Advances in Computing Research
, 1984
"... Planar embedding with minimal area of graphs on an integer grid is an interesting problem in VLSI theory. Valiant [12] gave an algorithm to construct a planar embedding for trees in linear area, he also proved that there are planar graphs that require quadratic area. We fill in a spectrum between Va ..."

Planar graphs as VPGgraphs
, 2013
"... A graph is BkVPG when it has an intersection representation by paths in a rectangular grid with at most k bends (turns). It is known that all planar graphs are B3VPG and this was conjectured to be tight. We disprove this conjecture by showing that all planar graphs are B2VPG. We also show that th ..."

Random planar graphs
 JOURNAL OF COMBINATORIAL THEORY, SERIES B 93 (2005) 187 –205
, 2005
"... We study various properties of the random planar graph Rn, drawn uniformly at random from the class Pn of all simple planar graphs on n labelled vertices. In particular, we show that the probability that Rn is connected is bounded away from 0 and from 1. We also show for example that each positive i ..."

Supereulerian planar graphs
, 2003
"... We investigate the supereulerian graph problems within planar graphs, and we prove that if a 2edgeconnected planar graph G is at most three edges short of having two edgedisjoint spanning trees, then G is supereulerian except a few classes of graphs. This is applied to show the existence of spann ..."

On Random Planar Graphs, the Number of Planar Graphs and Their Triangulations
 Jombinatorial Theory, Series B
, 2001
"... Let Pn be the set of labelled planar graphs with n vertices. Denise, Vasconcellos and Welsh proved that jPn j n! 75:8 n+o(n) and Bender, Gao and Wormald proved that jPn j n! 26:1 n+o(n) . McDiarmid proved that almost all graphs in Pn have at least 13=7n edges. In this paper, we show that jPn j n! 37 ..."

Matched Drawings of Planar Graphs
