Lenhart, Advisor A thesis submitted in partial ful llment of the requirements for the WebAbstract. A 1-planar graph is a graph that can be drawn in the Euclidean plane such that each edge crosses at most one edge. An independent crossing (IC)-planar graph is a 1-planar graph satisfying the condition that two pairs of crossing edges have no common end-vertices. It is shown in this paper that every IC-planar graph is 6-choosable. imdb actress

WebWe characterize embeddings of maximal NIC-planar graphs in terms of generalized planar dual graphs. The characterization is used to derive tight bounds on the density of maximal NIC-planar graphs which ranges between 3:2(n 2) and 3:6(n 2). Further, we show that optimal NIC-planar graphs with 3:6(n 2) edges have a unique embedding and can Web15 de jul. de 2024 · Request PDF On (p, 1)-Total Labelling of NIC-Planar Graphs A graph is NIC-planar if it can be drawn in the plane so that there is at most one crossing per … imdb actress 1.75m australiaWebconcepts and graph drawing.
