Abstract

The *reciprocal complement* R(D)R(D) of an integral domain DD is the subring of its fraction field generated by the reciprocals of its nonzero elements. Many properties of R(D)R(D) are determined when DD is a polynomial ring in n2n\geq 2 variables over a field. In particular, R(D)R(D) is an nn-dimensional, local, non-Noetherian, non-integrally closed, non-factorial, atomic G-domain, with infinitely many prime ideals at each height other than 00 and nn.
