| Abstract: | In this paper an opposite example is given at first in order to prove that there may be no extreme point in bounded closed convex in conjugate space X.In this this way it shows 2] ch. 2 of Lemma 3 is incorrect and points out the conditions that make the conclusion of this lemma tanable. |
