 Some results on integer-valued polynomials over modules Bull. Korean Math. Soc. 2020 Vol. 57, No. 5, 1165-1176 https://doi.org/10.4134/BKMS.b190846Published online September 30, 2020 Ali Reza Naghipour, Javad Sedighi Hafshejani Shahrekord University; Shahrekord University Abstract : Let $M$ be a module over a commutative ring $R$. In this paper, we study $\Int(R,M)$, the module of integer-valued polynomials on $M$ over $R$, and $\Int_{M}(R)$, the ring of integer-valued polynomials on $R$ over $M$. We establish some properties of Krull dimensions of $\Int(R,M)$ and $\Int_{M}(R)$. We also determine when $\Int(R,M)$ and $\Int_{M}(R)$ are nontrivial. Among the other results, it is shown that $\Int(\mathbb{Z},M)$ is not Noetherian module over $\Int_{M}(\mathbb{Z})\cap\Int(\mathbb{Z})$, where $M$ is a finitely generated $\mathbb{Z}$-module.
