英文摘要
One of the aims of this study is to construct a new theory of degeneration of Cohen-Macaulay modules based on the algebraic definition of degeneration. To study the degeneration of Cohen-Macaulay modules we have given careful consideration to the analogue of degeneration in the stable category. We have proved that this analogue in the stable category is easier in the actual computation. Using this idea we observed a lot of examples of degeneration of modules.
