چکیده

Abstract. let m be a right module over a ring r, m a pre-radical on [m], and n 2 [m]. in this note we show that ifn1;n2 2 [m] are two m-lifting modules such that ni is nj -projective (i; j = 1; 2), then n = n1 n2 is m-lifting. weinvestigate when homomorphic image of a m-lifting module is m-lifting.
