## Abstract The results of the drone‐fermion representation (DFR) in application to the Heisenberg ferromagnet with spin 1/2 are compared with the corresponding results obtained by means of Pauli operators. The expressions calculated in DFR by Spencer for the perturbational expansion of the one‐par
