On weakly-supplemented subgroups and the solvability of finite groups. (English) Zbl 07088787

Summary: A subgroup \(H\) of a finite group \(G\) is weakly-supplemented in \(G\) if there exists a proper subgroup \(K\) of \(G\) such that \(G=HK\). In this paper, some interesting results with weakly-supplemented minimal subgroups or Sylow subgroups of \(G\) are obtained.
