标题： Fibered toric varieties

摘要： 如果一个环面簇可以表示为环面底空间和环面纤维的纤维丛的全空间，则称为纤维化的环面簇。 纤维化的环面簇是环面簇丛的一个特例。 在本文中，我们首先介绍纤维化环面簇这一类。 然后，我们用它们来说明关于一般环面簇丛的拓扑和相交理论的一些已知和猜想结果。 最后，利用纤维化环面簇的语言，我们计算了光滑完备环面簇的等变上同调环。 显示英文摘要

摘要： A toric variety is called fibered if it can be represented as a total space of fibre bundle over toric base and with toric fiber. Fibered toric varieties form a special case of toric variety bundles. In this note we first give an introduction to the class of fibered toric varieties. Then we use them to illustrate some known and conjectural results on topology and intersection theory of general toric variety bundles. Finally, using the language of fibered toric varieties, we compute the equivariant cohomology rings of smooth complete toric varieties.
