We show that a ring R is nil 3-Armendariz ring if and only if for any , Tn(R) is nil 3-Armendariz ring. Also we prove that a right Ore ring R is nil 3-Armendariz if and only if so is Q, where Q is the classical right quotient ring of R. With the help of this result, we can show that a commutative ring R is nil 3-Armendariz if and only if the total quotient ring of R is nil 3-Armendariz.展开更多
It is proved that a left QF-2 ring R is QF if R is either an artinian strongly right bounded ring, or a finite strongly left bounded and left Kasch ring with Soc(RR) = Soc( RR).
