    • openAccess   Conjugacy classes and union of cosets of normal subgroups 

      Beltrán, Antonio Springer (2023)
      Let G be a finite group, N a normal subgroup of G and K a conjugacy class of G. We prove that if K ∪ K −1 is union of cosets of N, then N is soluble, K is a real-imaginary class, that is, every irreducible character of ...
