本文引入了一类对数概型(在方丹,Illusie和Kato意义下)的态射,并研究了它们的模.然后,应用这一点,我们定义了环面代数栈的概念,它可以被视为环面嵌入的框架内的代数栈,并证明了一些基本性质。此外,我们还研究了环面嵌入的堆叠理论模拟。
In this paper we will introduce a certain type of morphisms of log schemes (in the sense of Fontaine, Illusie and Kato) and study their moduli. Then by applying this we define the notion of toric algebraic stacks, which may be regarded as torus emebeddings in the framework of algebraic stacks and prove some fundamental properties. Also, we study the stack-theoretic analogue of toroidal embeddings.
