论文摘要
我们表明，Lusztig的规范基础是Grassmannian坐标环的两个部分，由SL（K）Web图给出。同等地，我们表明，GR（K，N）的每个SL（2）Web Immanant都是SL（K）Web不变的。
We show that Lusztig's canonical basis for the degree two part of the Grassmannian coordinate ring is given by SL(k) web diagrams. Equivalently, we show that every SL(2) web immanant of a plabic graph for Gr(k,n) is an SL(k) web invariant.
