4-连通平面图是$B_3$ - EPG

4-connected planar graphs are in $B_3$-EPG

Therese Biedl, Claire Pennarun

摘要:

我们证明了每个4-连通平面图都有一个$B_3$ -EPG表示,即,每个顶点由网格上的曲线表示,最多具有三个弯曲,并且当且仅当相应的曲线共享网格的边时,两个顶点相邻。我们的建设是基于修改的表示触摸加厚$L$ -形状Gonçalves等人提出的。

英文摘要:

We show that every 4-connected planar graph has a $B_3$-EPG representation, i.e., every vertex is represented by a curve on the grid with at most three bends, and two vertices are adjacent if and only if the corresponding curves share an edge of the grid. Our construction is based on a modification of the representation by touching thickened $L$-shapes proposed by Gonçalves et al.
