摘要
研究了交叉积R*G和次环,证明了R*G是半素G o ld ie环当且仅当R是半素G o ld ie环.在R为半素G o ld ie环的前提下,证明了R是G-极大次环当且仅当R*G是分次极大次环.最后给出了R*G为素环的一个等价条件.
In this paper, crossed products and orders are discussed. It is shown that R * G is a semiprime Goldie ring if and only if R is a semiprime Goldie ring, and that R* G is a graded maxmal order if and only if R is a G-maximal order. Finally, a necessary and sufficient condition for R * G to be prime is given.
