论文摘要
我们使用一维仪表组研究K理论GLSM不变性，并引入椭圆中心的电荷，该电荷取决于椭圆形的椭圆形小体和称为椭圆形的brane和水平结构的选择。这些中心电荷具有与椭圆形插入问题和满足自然Q差异方程的插值问题相关的积分表示。整体代表导致中央电荷在GLSM的两个不同阶段的壁交叉陈述。我们解释了Orbifold结构如何导致常规（K理论）和椭圆中央电荷的壁交叉之间的差异。
We study K-theoretic GLSM invariants with one-dimensional gauge group and introduce elliptic central charges that depend on an elliptic cohomology class called an elliptic brane and a choice of level structure. These central charges have an integral representation related to an interpolation problem for the elliptic brane and satisfy natural q-difference equations. Integral representaions lead to the wall crossing statement for the central charges in two different phases of the GLSM. We explain how the orbifold structure leads to differences between wall crossing of the usual (K-theoretic) and elliptic central charges.
