Scalar and Vector Massive Fields in Lyra's Manifold
R. Casana, C. A. M. de Melo, B. M. Pimentel
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…

Equivalence of Many-Photon Green Functions in DKP and KGF Statistical Quantum Field Theories
V. Ya. Fainberg, B. M. Pimentel, J. S. Valverde
We prove the equivalence of many-photon Green functions in statistical quantum field Duffin-Kemmer-Petiau (DKP) and Klein-Gordon-Fock (KGF) theories using functional path integral…

Thermodynamic Properties of the Relativistic Composite String - Expository Remarks
I. Brevik, A. A. Bytsenko, B. M. Pimentel
The Casimir energy for the transverse oscillations of a piecewise uniform closed string is calculated. The great adaptability of this string model with respect to various regulariz…
