Galactic Nonlinear Dynamic Model
C. A. M. de Melo, S. T. Resende
We develop a model for spiral galaxies based on a nonlinear realization of the Newtonian dynamics starting from the momentum and mass conservations in the phase space. The radial s…

Gauge Formulation for Higher Order Gravity
R. R. Cuzinatto, C. A. M. de Melo, L. G. Medeiros +1
This work is an application of the second order gauge theory for the Lorentz group, where a description of the gravitational interaction is obtained which includes derivatives of t…

Massless DKP field in Lyra manifold
R. Casana, C. A. M. de Melo, B. M. Pimentel
Massless scalar and vector fields are coupled to Lyra geometry by means of Duffin-Kemmer-Petiau (DKP) theory. Using Schwinger Variational Principle, equations of motion, conservati…
