Abstract

In this comment, we show that some assertions made in Bayoumi and Ibedou (2002)
[1] and Bayoumi and Ibedou (2002) [2] are incorrect. Specifically, one implication from Theorem 3.1
made in Bayoumi and Ibedou (2002) [1] is erroneous. Consequently, Propositions 5.1 and 6.1 intro-
duced in Bayoumi and Ibedou (2002) [2] are incorrect. In addition, one implication from Theorems
5.1 and 6.1, made in Bayoumi and Ibedou (2002) [2] are incorrect. We give some counterexamples to
support our claim.
