Abstract

In a Dedekind domain DD, every non-zero proper ideal AA factors as a product A=P1t1PktkA=P_1^{t_1}\cdots P_k^{t_k} of powers of distinct prime ideals PiP_i. For a Dedekind domain DD, the DD-modules D/PitiD/P_i^{t_i} are uniserial. We extend this property studying suitable factorizations A=A1AnA=A_1\dots A_n of a right ideal AA of an arbitrary ring RR as a product of proper right ideals A1,,AnA_1,\dots,A_n with all the modules R/AiR/A_i uniserial modules. When such factorizations exist, they are unique up to the order of the factors. Serial factorizations turn out to have connections with the theory of hh-local Pr\"ufer domains and that of semirigid commutative GCD domains.
