计算了环面簇上等变占优有理映射的所有相对动态度。我们使用Minkowski权的环簇的交理论。结果表明,相对动态度可以归结为环面簇上的动态度。因此,这些都是代数整数。
We compute all relative dynamical degrees of equivariant dominant rational maps on toric varieties. We use the intersection theory on toric varieties using Minkowski weights. As a result, we see that the relative dynamical degrees can be reduced to the dynamical degrees on toric varieties. Hence these are all algebraic integers.
