Abstract
The purpose of this paper is to study the behavior of the IN and SA property with respect to the skew power series and Laurent series extensions. For an α-compatible ring R it is shown that the skew power series ring is right SA if and only if R is right SA and satisfies the (SQA2) condition. Also it is shown that a semiprime ring R is right SA if and only if
is right SA. Moreover, if α is an automorphism, then we have similar results for skew Laurent series ring
Furthermore, if R is a reduced left Noetherian ring, then R is left IN if and only if
is left IN if and only if
is left IN. Also we present some examples to show that if we relax each assumption on R, our results can fail.
