给定一个固定的整数n,我们考虑H=GL(n,Z_p)的闭子群G,其中Z_p表示p元整数环,p是关于n的充分大的.假设G的Zariski闭包没有环面部分,我们给出了一个关于G的(Mod P)约化的条件,它保证G在H的Zariski闭包中有界指数.
Given a fixed integer n, we consider closed subgroups G of H = GL(n,Z_p) where Z_p denotes the ring of p-adic integers and p is sufficiently large in terms of n. Assuming that the Zariski closure of G has no toric part, we give a condition on the (mod p) reduction of G which guarantees that G is of bounded index in its Zariski closure in H.
