英文摘要
The final goal of this research is to answer the naive but important question of what non-Cohen-Macaulay rings are. The present targets are the following. (1) The study of quasi-socle ideals Q : mq, where m is the maximal ideal in a given Noetherian local ring and Q a parameter ideal in it. (2) The analysis of the graded rings associated to I = Q : mq. (3) The study of Gorenstein property in the Rees algebras of powers of parameter ideals. The achievements are summarized into 15 papers.
