Research ArticleOpen accessPhrase in the titleGraph Folding of Some Special GraphsE. El-Kholy, A. El-EsawyIn this study we introduced the definition of graph folding then, we proved that we cannot fold any complete graph except the bipartite graph. By using incidence matrices we described the graph folding. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 30 Mar 2010 · 7,351 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFolding of Trefoil Knot and its GraphM. El-Ghoul, A. I. Elrokh, M. M.A. ShamiriIn this study, we introduce the effect of the folding, conditional folding, retraction and conditional retraction on trefoil knot and its graph. We introduce the sheeted trefoil knot and the folding and retraction of this type and present the limit of foldings. We study how to obtain the types of link graph by adjacency matrix for any number of vertices … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2006 · 7,150 accessesView PDFCite
