本書講述了緊閉包理論及其應(yīng)用,緊閉包是一種通過約化到正特征來研究等特征環(huán)的方法。本書涵蓋了緊閉包的基本性質(zhì),包括各種類型的奇點,例如F正則奇點和F有理奇點;介紹了該理論的基本定理,包括Brian?on-Skoda定理的各個版本、各種同調(diào)猜想以及關(guān)于約化群不變量的Hochster-Roberts/Boutot定理。此外,本書還給出了該理論的一些應(yīng)用,包括大Cohen-Macaulay代數(shù)的存在性和各種一致Artin-Rees定理。
本書適合于對交換環(huán)和交換代數(shù)感興趣的研究生閱讀,也可供相關(guān)研究人員參考。
