论文摘要
该论文探讨了与复曲面品种(TPROJ A)相关的多式环A的Perling曲折Proj与同一环的Brenner和Schroer的同质频谱ProJMH A之间的关系。我们表明,总是有一个规范的开放式嵌入,并研究了它们是同构的标准。
The paper explores the relation between Perling's toric Proj of a multigraded ring A associated with a toric variety (tProj A), and Brenner and Schroer's homogeneous spectrum ProjMH A of the same ring. We show that there is always a canonical open embedding and study a criterion for them to be isomorphic.
