这项研究的带头人引入了广义紧闭包的概念,并成功地用交换环理论重新定义了乘子理想。准确地说,乘子理想是作为广义检验理想的极限给出的。在这项研究中,我们发现了测试理想和乘数理想的行为之间的几个差异。此外,为了研究交换代数理论中的几个不变量,我们推广了测试理想理论。
英文摘要
The leader of this research introduced the notion of a generalized tight closure and succeeded to redefine multiplier ideals in terms of commutative ring theory. Precisely speaking, the multiplier ideal is given as the limit of generalized test ideals. In this research, we found several differences between the behavior of test ideals and that of multiplier ideals. Moreover, we extended the theory of test ideals in order to study several invariants in the theory of commutative algebra.
