论文摘要
在本文中,我们研究了将圆环动作作为生育转变的几何实现的品种。我们为特定的一类生育转变提供了这些几何实现的明确结构,并研究了它们的某些几何特性,例如它们的MORI,NEF和可移动锥。
In this paper we study varieties admitting torus actions as geometric realizations of birational transformations. We present an explicit construction of these geometric realizations for a particular class of birational transformations, and study some of their geometric properties, such as their Mori, Nef and Movable cones.
