The crossing number cr(G) of a graph G is the smallest number of edge crossings in any drawing of G.In this paper, we prove that there exists a unique 5-regular graph G on 10 vertices with cr(G) = 2.This answers a question by Chia and Gan in the negative. 14 0 obj endobj endstream �� m82 << /Type /Page /Parent 1 0 R /LastModified (D:20210109033349+00'00') /Resources 2 0 R /MediaBox [0.000000 0.000000 595.276000 841.890000] /CropBox [0.000000 0.000000 595.276000 841.890000] /BleedBox [0.000000 0.000000 595.276000 841.890000] /TrimBox [0.000000 0.000000 595.276000 841.890000] /ArtBox [0.000000 0.000000 595.276000 841.890000] /Contents 11 0 R /Rotate 0 /Group << /Type /Group /S /Transparency /CS /DeviceRGB >> /Annots [ 4 0 R ] /PZ 1 >> V(P n) = fv 1;v 2;:::;v ngand E(P n) = fv 1v 2;:::;v n 1v ng.

In a simple graph, the number of edges is equal to twice the sum of the degrees of the vertices.
