Finite Solvable Groups in Which Only Two Nonlinear Irreducible Characters Have Equal Degrees Original Research Article

Berkovichet al.[Proc. Amer. Math. Soc.115(1992), 955–959] classified all groups in which the degrees of the nonlinear irreducible characters are distinct. In this paper we classify all solvable groups in which only two nonlinear irreducible characters have equal degrees (Theorem 7).
