局部log-正则环 vs. toric环

Local log-regular rings vs. toric rings

Shinnosuke Ishiro

AI总结:

本文旨在为对数几何中的一类Cohen-Macaulay局部环——局部log-正则环的环论性质(如典范模显式描述与因子类群有限生成性)提供纯交换环论证明。

摘要:

局部log-正则环是对数几何中处理的一类Cohen-Macaulay局部环。本文旨在为局部log-正则环的某些环论性质提供纯交换环论证明,例如典范模的显式描述以及因子类群的有限生成性。

英文摘要:

Local log-regular rings are a certain class of Cohen-Macaulay local rings that are treated in logarithmic geometry. Our paper aims to provide purely commutative ring theoretic proof of some ring-theoretic properties of local log-regular rings such as an explicit description of a canonical module, and the finite generation of the divisor class group.
