The density of states ϱ( E ) of a broad band ferromagnetic semiconductor in the vicinity of the Curie point is calculated by means of a computer solution of Dyson equation without vertex renormalization. Non‐quasipartical behavior of ϱ( E ) at E < 0 (convexivity of ϱ( E ), dϱ( E )/d E ≠ 0 at the edge) is found.
