چکیده
|
Let r be a ring and m a right r-module. we call m, a delta(m)-coretractable module if for every proper submodule n of m containing delta(m), there is a nonzero homomorphism from m=n to m. we investigate some conditions which under two concepts delta(m)-coretractable and coretractable coincide. for a ring r, we prove that r is right kasch if and only if r_r isdelta(r-r)-coretractable.
