We obtain information on torsion in Khovanov cohomology by performing calculations directly over [Formula: see text] for [Formula: see text] prime and [Formula: see text]. In particular, we get that the torus knots [Formula: see text] and [Formula: see text] contain torsion of order [Formula: see text] and [Formula: see text] in their Khovanov cohomology.

Khovanov 上同调中的扭转计算

我们通过直接在 [Formula: see text] 上针对 [Formula: see text] 素数和 [Formula: see text] 执行计算来获得 Khovanov 上同调中的扭转信息。特别是,我们得到环结[公式:见文本]和[公式:见文本]在它们的Khovanov上同调中包含阶数[公式:见文本]和[公式:见文本]的扭转。
