我们重新审视等变椭圆上同调中稳定包络的构造(阿甘加奇和奥昆科夫,《椭圆稳定包络》,arXiv:1604.00423),并在一种相当普遍的情形下对其存在性和唯一性给出了一个直接的归纳证明。我们还讨论了这种构造到等变K - 理论的特殊化。
We revisit the construction of stable envelopes in equivariant elliptic cohomology (Aganagic and Okounkov in Elliptic stable envelopes. arXiv:1604.00423) and give a direct inductive proof of their existence and uniqueness in a rather general situation. We also discuss the specialization of this construction to equivariant K-theory.
