在图形的扇形平面绘制中,一条边只能交叉具有共同端点的边。扇形平面图最近由Kaufmann和Ueckerdt引入,他们证明了每个n顶点的扇形平面图最多有5n-10条边,并且这个边界对于ni¾?20是紧的。从组合和算法的角度对其结果进行了推广。我们证明了扇形平面图约束版本密度的紧界,并研究了扇形平面度和k平面度之间的关系。同时,我们证明了在变量嵌入条件下扇平面性的测试是np完全的。
In a fan-planar drawing of a graph an edge can cross only edges with a common end-vertex. Fan-planar drawings have been recently introduced by Kaufmann and Ueckerdt, who proved that every n-vertex fan-planar drawing has at most 5n-10 edges, and that this bound is tight for ni¾?20. We extend their result from both the combinatorial and the algorithmic point of view. We prove tight bounds on the density of constrained versions of fan-planar drawings and study the relationship between fan-planarity and k-planarity. Also, we prove that testing fan-planarity in the variable embedding setting is NP-complete.
