Multi-symbolic Rees algebras and strong F-regularity | Anurag K. Singh
; | Date: |
7 Oct 2002 | Journal: | Mathematische Zeitschrift, 235 (2000) 335-344 | Subject: | Commutative Algebra MSC-class: 13A30; 13A35; 13H10 | math.AC | Abstract: | Let I be a divisorial ideal of a strongly F-regular ring R. Watanabe asked if the symbolic Rees algebra R_s(I) is Cohen-Macaulay whenever it is Noetherian. We develop the notion of multi-symbolic Rees algebras, and use this to show that R_s(I) is indeed Cohen-Macaulay whenever a certain auxiliary ring is finitely generated over R. | Source: | arXiv, math.AC/0210093 | Services: | Forum | Review | PDF | Favorites |
