本文给出了Schubert类在等变K-理论和Lagrange Grassmannian的等变上同调中对T-不动点的限制的正公式。我们的公式依赖于Ghorpade-Raghavan的一个结果，它给出了Schubert簇在Lagrange Grassmannian的T-不动点附近的等变Grobner退化。
We give positive formulas for the restriction of a Schubert Class to a T-fixed point in the equivariant K-theory and equivariant cohomology of the Lagrangian Grassmannian. Our formulas rely on a result of Ghorpade-Raghavan, which gives an equivariant Grobner degeneration of a Schubert variety in the neighborhood of a T-fixed point of the Lagrangian Grassmannian.
