摘要
我们在图同调中进行了计算，以进一步理解弦链空间的拓扑，特别是计算了它们同调和同伦中有限维直和项的欧拉示性数。在此过程中，我们还确定了对称群在 的模包络的正 arity 分量上作用的超特征标。

备注
We changed the title, the abstract, and improved the exposition. We also added better explanations on the modular operads. This is the final version, which will appear in Homology, Homotopy and Applications. arXiv admin note: text overlap with arXiv:1504.00896
