Abstract	Let O-K-M-N-O be a short exact sequence of finitely generated R-modules, where R is a Noetherian semiperfect algebra. We mainly discussed such conditions that N is quasi-Koszul provided that K, M are quasi-Koszul, and K is quasi-Koszul provided that M, N are quasi-Koszul, which perfect the results of Green and Mart nez-Villa in 1996.
