Ideal-theoretic characterizations of valuation and Prüfer monoids

Franz Halter-Koch (2004)

Archivum Mathematicum

Similarity:

It is well known that an integral domain is a valuation domain if and only if it possesses only one finitary ideal system (Lorenzen $r$ -system of finite character). We prove an analogous result for root-closed (cancellative) monoids and apply it to give several new characterizations of Prüfer (multiplication) monoids and integral domains.

Generalized Schwarzian derivatives for generalized fractional linear transformations

Similarity:

Generalizations of the classical Schwarzian derivative of complex analysis have been proposed by Osgood and Stowe [12, 13], Carne [5], and Ahlfors [3]. We present another generalization of the Schwarzian derivative over vector spaces.

We prove that, for all integers $k$ exceeding some effectively computable number $K$ , the distance from ${(3 / 2)}^{k}$ to the nearest integer is greater than $0 . 5803^{k}$ .
