论文摘要
在本文中，我们证明罗林不变是在托雷利（Torelli）群体上引起同构形态的独特不变性。使用此结果，我们将Pitsch给出的Torelli组的Torelli组的琐碎的2 cocycles家族构建$ 3 $ -SPHERES，包括在Abelian Group上具有价值为$ 2 $ $ 2的不变性。
In this paper we prove that the Rohlin invariant is the unique invariant inducing a homomorphism on the Torelli group. Using this result we generalize the construction of invariants of homology $3$-spheres from families of trivial 2-cocycles on the Torelli group given by Pitsch to include invariants with values on an abelian group with $2$-torsion.
