摘要：The Kirchhoff index Kf() is the sum of the effective resistance distances between all pairs of vertices in . The hypercube and the folded hypercube are well known networks due to their perfect properties. The graph , constructed from , is the line graph of the subdivision graph . In this paper, explicit formulae expressing the Kirchhoff index of and are found by deducing the characteristic polynomial of the Laplacian matrix of in terms of that of .
