本文证明了Thompson关于一类无限李型单群E7(q)的一个猜想。更精确地说,我们证明了每个具有性质Z(G)= 1和cs(G)= cs(E7(q))的有限群G必然同构于E7(q),其中cs(G)和Z(G)分别是G的共轭类的长度和G的中心.
In this article, we prove a conjecture of Thompson for an infinite class of simple groups of Lie type E7(q). More precisely, we show that every finite group G with the properties Z(G) = 1 and cs(G) = cs(E7(q)) is necessarily isomorphic to E7(q), where cs(G) and Z(G) are the set of lengths of conjugacy classes of G and the center of G respectively.
