## Abstract

H. Dye defined certain projections P_{i} _{,} _{j}(a) of a C^{∗} -matrix algebra M_{n}(A), and he used it to prove that any isomorphism between unitary groups of von Neumann factors is implemented by a ∗ -isomorphism. In this paper we study actions of some ∗ -isomorphism on the projections P_{i} _{,} _{j}(a). Indeed, we deduce results related to the Cuntz algebras and its unitary groups.
