    In [Math. USSR, Izv. 11, 221--238 (1977; Zbl 0378.13002)] \textit{A. A. Suslin} studied the action of the group \(E_n(A)\) on \(U_{m_n(A)}\) over a Noetherian ring, where \(A=R[X_1^{\pm 1},\dots,X_k^{\pm 1}, X_{k+1},\dots,X_m]\). In this paper author studies the action of group \(E_n(A)\) on \(U_{m_n(A)}\) over non-Noetherian ring, i.e., over a commutative ring of Krull dimension zero. In particular, they show that every stably free module over \(A\) is free, i.e., \(A\) is a Hermite ring.
