A drawing D of a graph is called 1- planar if each edge in D is crossed at most once. If a graph has a 1-planar drawing, then it is called 1- planar. The notion of 1-planarity was introduced in 1965 by Ringel [ 13 ], and since ...

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 WebWe study the following classes of beyond-planar graphs: 1-planar, IC-planar, and NIC-planar graphs.
