Abstract (EN):
Let R be a Noetherian commutative ring and ¿1,...,¿n commuting automorphisms of R. Define T = R[¿1,...,¿n;¿ 1,...,¿n] to be the skew-polynomial ring with ¿ir = ¿i(r)¿i and ¿i¿j = ¿j¿i, for all i, j ¿ {1,...,n} and r ¿ R, and let S = R[¿1,¿1 -1,...,¿ n,¿n -1;¿ 1,...,¿n] be the corresponding skew-Laurent ring. In this paper we show that S and T satisfy the strong second layer condition and characterize the links between prime ideals in these rings. Copyright © 1997 by Marcel Dekker, Inc.
