We prove the equivalence of many-gluon Green functions inDuffin-Kemmer-Petieu and Klein-Gordon-Fock statistical quantum field theories.The proof is based on the functional integral formulation for the statisticalgenerating functional in a finite-temperature quantum field theory. As anillustration, we calculate one-loop polarization operators in both theories andshow that their expressions indeed coincide.Comment: 8 page
