摘要
本文引进了环的左自由正规化扩张和拟Excelent扩张,并将环的Excelent扩张的一些性质推广到了左自由正规化扩张和拟Excelent扩张,主要讨论了几乎Noether性,正则性,凝聚性和半遗传性.
The left free normalizing extension andquasi-excellent extension of a ring are introduced. Some properties ofexcellent extension of a ring are generalized to left free normalizingextension and quasi-excellent extension. The main results are about thealmost Noetherian property, regularity, coherent property andsemiheredity.
