Abstract: The author studies the stabilization for the unitary groups over polynomial rings and obtains for them some results analogous to the results of linear groups and symplectic groups. It is especially proved that $K_1 U(A) = K_1 U(R)$ where $A = R[X_1, \cdots, X_m]$, $R$ is a ring of algebraic integers in a quadratic field $Q(\sqrt d)$.

Keywords:

Stabilization theorem, Unitary group, Polynomial ring.
