The crossing number of locally twisted cubes

Combinatorics 2015-03-19 v1

Abstract

The {\it crossing number} of a graph GG is the minimum number of pairwise intersections of edges in a drawing of GG. Motivated by the recent work [Faria, L., Figueiredo, C.M.H. de, Sykora, O., Vrt'o, I.: An improved upper bound on the crossing number of the hypercube. J. Graph Theory {\bf 59}, 145--161 (2008)] which solves the upper bound conjecture on the crossing number of nn-dimensional hypercube proposed by Erd\H{o}s and Guy, we give upper and lower bounds of the crossing number of locally twisted cube, which is one of variants of hypercube.
