New group structures for Carbon onions and Carbon nanotubes via affine   extensions of non-crystallographic Coxeter groups
  We present results underlining the conjecture that affine extensions for non-crystallographic Coxeter groups are suitable mathematical objects for the description of the symmetries of Carbon onions and Carbon nanotubes. It is the hope that these considerations will shed new light on open questions concerning structure, stability and formation of these fullerenes.
