这是 Damien Calaque 和作者的“Hochschild 上同调和 Atiyah 类”的配套注释。使用基本方法，我们计算辐条向外的车轮的 Kontsevich 重量。结果以修正的伯努利数表示。 Torossian 早些时候（未发表）以及 Thomas Willwacher 最近使用更先进的方法也获得了相同的结果。
This is a companion note to “Hochschild cohomology and Atiyah classes” by Damien Calaque and the author. Using elementary methods we compute the Kontsevich weight of a wheel with spokes pointing outward. The result is in terms of modified Bernoulli numbers. The same result had been obtained earlier by Torossian (unpublished) and also recently by Thomas Willwacher using more advanced methods.
