SKEW QUASI BAER SKEW POLYNOMIAL RINGS

A ring R with an automorphism ¾ is called ¾-quasi Baer if the right annihilator of every ¾-invariant ideal of R is generated by an idempotent, as a right ideal. We show the left-right symmetry of ¾-quasi Baer condition and prove R is ¾-Baer if and only if R[x; ¾] is ¯¾-quasi Baer.
