证明了:若R是半质环,α是R上无限循环群的部分作用,则R是右Goldie当且仅当R[x; α]是右Goldie当且仅当R <$x; α <$是右Goldie,其中R[x; α](R <$x; α <$)表示R上的部分斜(Laurent)多项式环.此外,R <$x; α <$是半素的,而R[x; α]不一定是半素的。
We prove that if R is a semiprime ring and α is a partial action of an infinite cyclic group on R, then R is right Goldie if and only if R[x; α] is right Goldie if and only if R⟨x; α⟩ is right Goldie, where R[x; α] (R⟨x; α⟩) denotes the partial skew (Laurent) polynomial ring over R. In addition, R⟨x; α⟩ is semiprime while R[x; α] is not necessarily semiprime.
