Denote by T and I-alpha the bilinear Calderon-Zygmund operators and bilinear fractional integrals, respectively. In this paper, it is proved that if b......

In this paper we prove that a finite group in which all non-nilpotent maximal subgroups are normal must have a Sylow tower, which improves Theorem 1.3......
