Log minimal models for arithmetic threefolds | Posted on:2017-05-14 | Degree:Ph.D | Type:Dissertation | University:The University of Utah | Candidate:Egbert, Paul Andrew | Full Text:PDF | GTID:1458390008973228 | Subject:Mathematics | Abstract/Summary: | | I study the existence of log minimal models for a Kawamata log-terminal pair of relative dimension two over a Dedekind domain. This generalizes the semistable result of Kawamata. Also I prove a result on the invariance of log plurigenera for such pairs, generalizing the result of Suh. To extend the result from discrete valuation rings to Dedekind domains, some computability results are given for basepoint-freeness, vanishing of cohomology, and finite generation of log-canonical and adjoint rings on a mixed characteristic family of surfaces. | Keywords/Search Tags: | Log | | Related items |
