Abstract

\DeclareMathOperator\IntInt\DeclareMathOperator\IntRIntR\DeclareMathOperator{\Int}{Int}\DeclareMathOperator{\IntR}{Int{}^\text{R}}For a domain DD, the ring \Int(D)\Int(D) of integer-valued polynomials over DD is atomic if DD satisfies the ascending chain condition on principal ideals. However, even for a discrete valuation domain VV, the ring \IntR(V)\IntR(V) of integer-valued rational functions over VV is antimatter. We introduce a family of atomic rings of integer-valued rational functions and study various factorization properties on these rings.
