Moreover, a condition for finitely generated projec-tive T-modules to have n in the stable range is given under the assumption that A and B are exchange rings.展开更多

We present the equivalent definition of h_M(X), the sufficient and necessary conditions under which l_^(M) (X) is complete, and l_M(X) and h_M(X) are separable respectively, and also give the sufficient condition that h_M(X) has a basis. All these results generalize the results for the classical Orlicz sequence spaces.展开更多
