Extensions of Baer and quasi-Baer modules

Abstract. We study the relationships between the Baer, quasi- Baer and p.q.-Baer property of an R-module M and the polynomial extensions of module M. As a consequence of our results, we obtain some results of [C.Y. Hong, N.K. Kim and T.K. Kwak, J. Pure Appl. Algebra 151 (2000) 215-226.] and [E. Hashemi and A. Moussavi, Acta Math.
