Abstract: Theorem 5 yields the condition sufficient for a group to be a direct product of a $\pi $-group and an abelian $\pi '$-group. We also obtain characterizations of nilpotent groups, prime power groups, $p$-nilpotent and $p$-closed groups in the language of characters. Proofs of some results depend on the classification of finite simple groups. Some problems are posed and discussed.
