所有非线性不可约特征标维数中恰有一个为合数的有限群,称为PPC^*群.对可解PPC^*群的导长及特征标维数中素数的个数进行了估计.
In this paper, the solvable groups in which only one of the nonlinear irreducible character degrees is composite number are considered. The authors evaluate the derived length and the number of prime in the set of the nonlinear irreducible character degrees.
