> | ### D.4.16 modnormal_lib Library: modnormal.lib Purpose: Normalization of affine domains using modular methods Authors: J. Boehm boehm@mathematik.uni-kl.de W. Decker decker@mathematik.uni-kl.de S. Laplagne slaplagn@dm.uba.ar G. Pfister pfister@mathematik.uni-kl.de A. Steenpass steenpass@mathematik.uni-kl.de S. Steidel steidel@mathematik.uni-kl.de Overview: Suppose A is an affine domain over a perfect field. This library implements a modular strategy for finding the normalization of A. Following [1], the idea is to apply the normalization algorithm given in [2] over finite fields and lift the results via Chinese remaindering and rational reconstruction as described in [3]. This approach is inherently parallel. The strategy is available both as a randomized and as a verified algorithm.
