我们计算了周期映射下ADE奇点的Milnor格象。我们还证明了Milnor格可以由相应奇点的Berglund-Hubsch对偶定义的适当的相对$K$-群来确定。
We compute the image of the Milnor lattice of an ADE singularity under the period map. We also prove that the Milnor lattice can be identified with an appropriate relative $K$-group defined through the Berglund--Hubsch dual of the corresponding singularity.
