And the main two results are: (1) R is a Bear (PP) ring if and only if R[[x]] is a Baer (PP) ring; (2) If R is an α-rigid ring, then R is a Baer (PP, PS) ring if and only if R[x, x^-1; α] is a Baer (PP, PS) ring.展开更多

文摘This paper gives some results on Strong-Armendariz rings and the Ore-extensions R[x,x^-1;α] of Bare, PP and PS rings. And the main two results are: (1) R is a Bear (PP) ring if and only if R[[x]] is a Baer (PP) ring; (2) If R is an α-rigid ring, then R is a Baer (PP, PS) ring if and only if R[x, x^-1; α] is a Baer (PP, PS) ring.
