论文摘要
让$ x $成为配备有圆环$ a $的动作的符号品种。令$ν\子集$为有限的环状子组。我们表明，可以通过$ x $的椭圆稳定信封的各种限制来获得$ x^ν\子集X $的k理论稳定信封。详细考虑了复杂平面中希尔伯特方案的$ x $的示例。
Let $X$ be a symplectic variety equipped with an action of a torus $A$. Let $ν\subset A$ be a finite cyclic subgroup. We show that K-theoretic stable envelope of subvarieties $X^ν\subset X$ can be obtained via various limits of the elliptic stable envelopes of $X$. An example of $X$ given by the Hilbert scheme of points in the complex plane is considered in details.
