The resonance graphs of nanotubes and toroidal polyhexes
Lingmei Liang, Heping Zhang
Coronoid systems, nanotubes and toroidal polyhexes (or fullerenes) can all be regarded as carbon networks composed of carbon atoms linked in hexagonal shapes. The resonance graphs…

The resonance graphs of coronoid systems and nanotubes
Lingmei Liang, Heping Zhang
The resonance graph of a hexagonal system is connected, which shows that a perfect matching can be transformed into any other perfect matchings by a series of flips along hexagons.…
