In this paper we are concerned with the computation of prime decomposi
tions of radicals in polynomial rings over a noetherian commutative ri
ng R with identity. We show that prime decomposition algorithms in R c
an be liked to R[x] if for every prime ideal P in R univariate polynom
ials can be factored over the quotient field of the residue class ring
R/P. In the proof of this result a liking algorithm is constructed wh
ich can be considered as a generalization of the algorithm of Ritt and
Wu.
