Irreducibility of ideals in a one-dimensional analytically irreducible ring

Valentina Barucci, Faten Khouja (2010)

Actes des rencontres du CIRM

Let R be a one-dimensional analytically irreducible ring and let I be an integral ideal of R . We study the relation between the irreducibility of the ideal I in R and the irreducibility of the corresponding semigroup ideal v ( I ) . It turns out that if v ( I ) is irreducible, then I is irreducible, but the converse does not hold in general. We collect some known results taken from [5], [4], [3] to obtain this result, which is new. We finally give an algorithm to compute the components of an irredundant decomposition...
