The edge-Wiener index of zigzag nanotubes

作者：

Highlights：

• We find explicit closed formulae for the edge-Wiener index of zigzag nanotubes.

• The method of computing the edge-Wiener index of a zigzag nanotube is to compute the Wiener index of the line graph of zigzag nanotube.

• The technique of computation is to divide the vertices of the line graph into some levels.
