Abstract

If N1 is a nearring, V is a faithful tame N1-module and N2 is a nearring containing N1 such that V is a faithful tame N2-module and the N1- and N2-ideals of V coincide, we study when N1-isomorphic minimal factors of V are N2-isomorphic. We also study a stronger form of such preservation called type preservation. Particular attention is paid to the case where N2 is the nearring of 0-preserving and congruence preserving functions of V , C0(V ). Here we will see that isomorphism preservation is related to centralizers of minimal factors relative to C0(V ) which then motivates the study of these centralizers as well.

近模最小因子的集中器和同构保持

摘要

如果N 1是近环,V是忠实驯服N 1 -模并且N 2是包含N 1 的近环,使得V是忠实驯服N 2 -模并且VN 1 - 和N 2 -理想重合,我们研究了当V 的N 1 -同构最小因子是N 2 -同构时。我们还研究了一种更强的这种保存形式,称为类型保存。特别注意N 2V , C 0 ( V )的保零和保同函数的接近。在这里,我们将看到同构保持与相对于C 0 ( V )的最小因子的中心化器有关,这也激发了对这些中心化器的研究。
