Factorizations of polynomials with integral non-negative coefficients

Federico Campanini, Alberto Facchini

We study the structure of the commutative multiplicative monoid $N_{0} [x]^{*}$ of all the non-zero polynomials in $Z [x]$ with non-negative coefficients. We show that $\…

On bi-amalgamated constructions

Federico Campanini, Carmelo Antonio Finocchiaro

Let $f : A ⟶ B, g : A ⟶ C$ be ring homomorphisms and let $b$ (resp., $c$ ) be an ideal of $B$ (resp., $C$ ) satisfying $f^{-1}(\mathfrak{b…

Some remarks on Prüfer rings with zero-divisors

Federico Campanini, Carmelo Antonio Finocchiaro

Let $A$ be the fiber product $R \times_{T} B$ , where $B \to T$ is a surjective ring homomorphism with regular kernel and $R \subseteq T$ is a ring extension where $T$ is an overring of $…
