چکیده
Regarding non-unique factorization of integer-valued polynomials over a discrete valuation domain (R,M) with finite residue field, it is known that there exist absolutely irreducible elements, is, elements all whose powers factor uniquely, and non-absolutely elements. We completely constructively characterize the among split polynomials. They correspond bijectively to sets, which we call balanced, characterized by combinatorial property regarding distribution their classes M. For each such balanced set as roots polynomial, exists unique vector multiplicities constant so corresponding product monic linear factors times an polynomial. This also yields sufficient criteria for Dedekind domains be irreducible.

On the factorization of polynomials over discrete valuation domains
We study some factorization properties for univariate polynomials with coefficients in a discrete valuation domain (A, v). We use some properties of the Newton index of a polynomial F (X) = ∑d i=0 aiX d−i ∈ A[X] to deduce conditions on v(ai) that allow us to find some information on the degree of the factors of F .
متن کاملInteger-valued Polynomials over Quaternion Rings
When D is an integral domain with field of fractions K, the ring Int(D) = {f(x) ∈ K[x] | f(D) ⊆ D} of integer-valued polynomials over D has been extensively studied. We will extend the integer-valued polynomial construction to certain noncommutative rings. Specifically, let i, j, and k be the standard quaternion units satisfying the relations i = j = −1 and ij = k = −ji, and define ZQ := {a+bi+...
متن کاملFiltered Modules over Discrete Valuation Domains
We consider a uni ed setting for studying local valuated groups and coset-valuated groups, emphasizing the associated ltrations rather than the values of elements. Stable exact sequences, projectives and injectives are identi ed in the encompassing category, and in the category corresponding to coset-valuated groups.
متن کاملGeneralizations of Dedekind domains and integer-valued polynomials
This talk will provide a snapshot of contemporary commutative algebra. In classical commutative algebra and algebraic number theory, the Dedekind domains are the most important class of rings. Modern commutative algebra studies numerous generalizations of the Dedekind domains in attempts to generalize results of algebraic number theory. This talk will introduce a few important generalizations o...
