We describe stable cup-i products on the cochain complex with $F^2$ coefficients of any augmented semi-simplicial object in the Burnside category. An example of such an object is the Khovanov functor of Lawson, Lipshitz and Sarkar. Thus we obtain explicit formulas for cohomology operations on the Khovanov homology of any link.

Khovanov 同源性的更高 Steenrod 平方

我们用 Burnside 类别中任何增强半单纯对象的 $F^2$ 系数描述了 cochain 复合体上的稳定 cup-i 产品。此类对象的一个​​示例是 Lawson、Lipshitz 和 Sarkar 的 Khovanov 函子。因此,我们获得了对任何链接的 Khovanov 同源性的上同调运算的明确公式。
