论文摘要
我们定义了$ sl_2（\ mathbb {r}）$ - 封闭3个manifolds的卡森不变。我们还可以观察到计算不变型的程序。我们讨论了给卡森不变一些等级的一些方法。
We define an $SL_2(\mathbb{R})$-Casson invariant of closed 3-manifolds. We also observe procedures of computing the invariants in terms of Reidemeister torsions. We discuss some approach of giving the Casson invariant some gradings.
