Abstract:

We let $D$ be a local (noetherian) one-dimensional unibranched domain, $K$ its quotient field, $\mathfrak {m}$ its maximal ideal, ${D’}$ its integral closure, and ${\mathfrak {m}’}$ the maximal ideal of ${D’}$. If $E$ is a subset of $K$, we let $\operatorname {Int} (E,D)$ be the set of integer-valued polynomials on $E$, thus $\operatorname {Int} (E,D) = \{ f \in K[X]|f(E) \subset D\}$. For a fractional subset $E$ of $D$ (i.e., there is a nonzero element $d$ of $D$ such that $dE \subset D$), we show that the prime ideals of $\operatorname {Int} (E,D)$ above $\mathfrak {m}$ are in one-to-one correspondence with the elements of the topological closure of $E$ in the completion of $K$ for the ${\mathfrak {m}’}$-adic topology.
