The Schreier Property and Gauss' Lemma
Let be an integral domain with quotient field . Recall that is Schreier if is integrally closed and for all , implies that where e . A GCD domain is Schreier. We show that an integral domain is a GCD domain if and only if (i) for each pair , there is a finitely generated ideal such that and (ii) every quadratic in that is a product of two linear polynomials in is a product of two linear polynomials in . We also show that is Schreier if and only if every polynomial...

Unique factorization in non-atomic integral domains
In un UFD ogni elemento non unitario può essere espresso in modo unico nella forma dove è un elemento unitario, i sono primi non associati e ogni . Per studiare questa fattorizzazione in un ambito non atomico, si prende in esame un certo numero di generalizzazioni della potenza di un primo . Per numerose di queste generalizzazioni si prova che si ottiene una forma di fattorizzazione unica e la si mette in relazione, nel caso in cui è un dominio di integrità, con rappresentazioni di carattere...
