چکیده
We prove the equivalence of many-photon Green functions in statistical quantum field Duffin-Kemmer-Petiau (DKP) and Klein-GordonFock (KGF) theories using functional path integral formalism for partition functional in statistical quantum (finite temperature) field theory. We also calculate the polarization operators in these theories in oneloop approximation, and demonstrate their coincidence.

We prove the equivalence of many-gluon Green functions in DuffinKemmer-Petieu (DKP) and Klein-Gordon-Fock (KGF) statistical quantum field theories. The proof is based on the functional integral formulation for the statistical generating functional in a finite-temperature quantum field theory. As an illustration, we calculate one-loop polarization operators in both theories and show that their e...

The thermodynamical partition function of the Duffin–Kemmer–Petiau theory is evaluated using the imaginary-time formalism of quantum field theory at finite temperature and path integral methods. The DKP partition function displays two features: (i) full equivalence with the partition function for charged scalar particles and charged massive spin 1 particles; and (ii) the zero mode sector which ...

In this work we will present a method to employ a duality mechanism via introduction of gauge condensates on fully quantized topological Schwarz type actions. The restrictions in implementing this equivalence at quantum level is discussed and, some three-dimensional examples are presented.
