| Abstract: | Let G be a nonelementary,discrete subgroup of PU(2,1) and the dimension of the space spanned by all the representative vectors of the fixed points of loxodromic elements of G is 3,then the normalizer N of G is discrete in PU(2,1).We also give an example to show that the condition is necessary. |
