| Abstract: | In this paper, we prove that the isometrically algebraic isomorphism between two subalgebras of AF algebras with property of double commutant can be extended to an * isomorphism between their enveloping C* algebras. Consequently, the problem raised from 4] Remark2.12 can be solved affirmatively. |
