摘要翻译:
我们用拟方块定义了复分层的概念,并证明了这类空间以复商的形式出现在与凸多边形相关的环面的某些非闭子群上。由此得到的空间提供了与有理凸多面体有关的复角变化概念的非理性情形的自然推广。

英文摘要:
We define the notion of complex stratification by quasifolds and show that such spaces occur as complex quotients by certain nonclosed subgroups of tori associated to convex polytopes. The spaces thus obtained provide a natural generalization to the nonrational case of the notion of toric variety associated with a rational convex polytope.
