Let G be an infinite group. If G has a normal elementary abelian subgroup, then G is irrecognizable.

设G是无限,若G存在正规初等换子,则G是不可分辨的.

Using the notion of coefficient matrix and maximal element.We prove that the Lie algebra is semi-simple and it has no abelian two dimensional subalgebra.

利用系矩阵和极大项，证明了这类是半单且没有二维换子。
