我们考虑一对由三维镜像对称相关的箭图簇$(X; X')$,其中$X = T^*\text{Gr}(k,n)$是$n$维空间中$k$维平面的格拉斯曼流形的余切丛。我们给出了两边的椭圆稳定包络的公式。我们证明了在$X\times X'$上存在一个等变椭圆上同调类(母函数),它在$X$和$X'$上的限制分别是这些簇的椭圆稳定包络。这意味着,在将一边的等变参数与对偶边的凯勒参数进行转置和等同之后,$X$和$X'$的椭圆稳定包络的限制矩阵是相等的。
We consider a pair of quiver varieties (X;X') related by 3d mirror symmetry, where X =T*Gr(k,n) is the cotangent bundle of the Grassmannian of k-planes of n-dimensional space. We give formulas for the elliptic stable envelopes on both sides. We show an existence of an equivariant elliptic cohomology class on X $\times$ X' (the Mother function) whose restrictions to X and X' are the elliptic stable envelopes of those varieties. This implies, that the restriction matrices of the elliptic stable envelopes for X and X' are equal after transposition and identification of the equivariant parameters on one side with the Kahler parameters on the dual side.
