| Outline of Final Research Achievements |
The purpose of this research is to enrich the theory of one-dimensional almost Gorenstein rings, which was originally studied by Barucci-Froeberg and Goto-Matsuoka-Phuong, and to develop the theory for higher dimension. Among them, we studied the almost Gorenstein property for Rees algebras, determinantal rings, and Arf rings. In parallel, we analyzed the sequentially Cohen-Macaulay property for the Rees algebras in order to make progress the theory of non-Cohen-Macaulay rings and modules.
