让$$G$G是一个实际上特殊的群体。则$$G$$G的剩余有限性增长至多是线性的。这个结果不能通过将$$G$$G嵌入到一个特殊的线性群中得到。实际上,特殊线性群$${{mathrm{SL}_k(mathbb {Z})$$SLk(Z),对于$$k > 2$$k>2,有剩余有限增长$$n^{k-1}$$nk-1。
Let $$G$$G be a virtually special group. Then the residual finiteness growth of $$G$$G is at most linear. This result cannot be found by embedding $$G$$G into a special linear group. Indeed, the special linear group $${{mathrm{SL}}}_k(mathbb {Z})$$SLk(Z), for $$k > 2$$k>2, has residual finiteness growth $$n^{k-1}$$nk-1.
