The results obtained extend Madden’s result for Dedekind domains to more general types of 1-dimensional Noetherian rings. In particular, these results apply to piecewise polynomial functions t:C → R where R is a real closed field and CRn is a closed 1-dimensional semi-algebraic set, and also to the associated “relative” case where t, C are defined over some subfield KR.
