We prove that for any prime homology $(d-1)$-sphere $\Delta$ of dimension $d-1\geq 3$ and any edge $e\in S$, the graph $G(\Delta)-e$ is generically $d$-rigid. This confirms a conjecture of Nevo and Novinsky.

同调球图减去一条边的刚性

我们证明对于维数为 $d-1\geq 3$ 的任何素同调 $(d-1)$-sphere $\Delta$ 和任何边 $e\in S$,图 $G(\Delta)-e $ 一般是 $d$-rigid。这证实了 Nevo 和 Novinsky 的猜想。
