COUNTEREXAMPLES FOR PROPERTIES OF LINE GRAPHS OF GRAPHS OF DIAMETER TWO


Harishchandra S. Ramane, Ivan Gutman




Some errors in a recently published paper [Ramane et al., Distance spectra and distance energies of iterated line graphs of regular graphs, {t Publ. Inst. Math.\/} {\bf 85} (2009) 39-46] are pointed out. These pertain to conditions under which the iterated line graphs of a graph of diameter two have also diameter two.
