论文摘要
我们考虑(标记)图的中文剩余定理。对于$ x $ a gkm $ t $ - 变量和$ y $不变的子变量,我们使用它来给出限制映射$ h^*(x)\ to h^*(y)$的过度条件。特别是,这适用于光滑的复曲面中某些不变的亚变化。
We consider a Chinese remainder theorem for (labeled) graphs. For $X$ a GKM $T$-variety and $Y$ an invariant subvariety, we use this to give a condition for surjectivity of the restriction map $H^*(X) \to H^*(Y)$. In particular, this applies to certain invariant subvarieties in a smooth toric variety.
