摘要:The problem of coupling between spin and torsion is analysed from a Lyra’s manifold background
for scalar and vector massive fields using the Duffin-Kemmer-Petiau (DKP) theory. We found the
propagation of the torsion is dynamical, and the minimal coupling of DKP field corresponds to a
non-minimal coupling in the standard Klein-Gordon-Fock and Proca approaches. The origin of
this difference in the couplings is discussed in terms of equivalence by surface terms.
