Geometric intersection graphs form an intriguing class of structures in which vertices represent geometric objects – such as line segments, discs, or curves – and an edge is established between two ...
Carpathian Journal of Mathematics, Vol. 39, No. 2 (2023), pp. 371-382 (12 pages) The crossing number cr(G) of a graph G is the minimum number of edge crossings over all drawings of G in the plane. In ...
