Locally Inertial Reference Frames in Lorentzian and Riemann-Cartan Spacetimes
J. F. T. Giglio, W. A. Rodrigues
In this paper we scrutinize the concept of locally inertial reference frames (LIRF) in Lorentzian and Riemann-Cartan spacetime structures. We present rigorous mathematical definiti…

Gravitation and Electromagnetism as Geometrical Objects of a Riemann-Cartan Spacetime Structure
J. Fernando T. Giglio, Waldyr A. Rodrigues
In this paper we first show that any coupled system consisting of a gravitational plus a free electromagnetic field can be described geometrically in the sense that both Maxwell eq…
