Abstract
It is proved by counter example that one of the theorems presented in
[FILOMAT 29:8 (2015), 1781-1788] does not always hold true. It is also
proved by counter example that the necessary condition given in Theorem 3.7
[If diam(H) = 2, then s(K1 ? H) = s(H)] mentioned in the above cited paper
does not hold true.
