On extended quasi-Armendariz rings
  This paper deals with the quasi-Armendariz ring in general setting. We generalize the notions of quasi-Armendariz and $\alpha$-skew Armendariz ring to quasi $\alpha$-Armendariz and quasi $\alpha$-skew Armendariz ring and investigate their properties. We also consider the quasi Armendariz properties of Laurent type rings.
