Change Details: In the third paragraph on p. 2421 and in Theorem 1��� of [3] it is wrongly assumed that ���the multiplication on a topological semigroup T can be extended to a right continuous multiplication on ��T ���; in other words, we wrongly assume that ��� ��T is a compact Hausdorff right-topological semigroup for any topological semigroup T ���. So using [3, Theorem 1] we can only obtain the following two theorems in place of [3, Theorem 1���], where X ��� denotes the limit-point set of a space X and J ( E ) denotes the set of all idempotents in a compact Hausdorff right-topological semigroup E .
