| Abstract: | The sufficient condition for that that the direct sum of two x-lifting modules will still be x-lifting module was discussed by introducing the concept of x-lifting module. As a corollary, such a sufficient condition that the direct sum of two lifting modules still is lifting one is obtained. |
