On unitary invariant subalgebras

1990
The author investigates the structure of subalgebras of simple Artinian algebras which are invariant with respect to the unitary group. Let \(R=M_ n(D)\), for D a division ring with center Z, and assume that char(R)\(\neq 2\) and that R has an involution, \({}^*\).
