On Dark Energy and Accelerated Reference Frames
S. C. Ulhoa
The paper is devoted to an explanation of the accelerated rate of expansion of the Universe. Usually the acceleration of the Universe, which is described by FRW metric, is due to d…
The electromagnetic field in accelerated frames
J. W. Maluf, F. F. Faria
We develop a geometrical framework that allows to obtain the electromagnetic field quantities in accelerated frames. The frame of arbitrary accelerated observers in space-time is d…
Conformally invariant teleparallel theories of gravity
J. W. Maluf, F. F. Faria
We analyze the construction of conformal theories of gravity in the realm of teleparallel theories. We first present a family of conformal theories which are quadratic in the torsi…
Homogeneous Solutions of Quadratic Gravity
Daniel Müller
It is believed that soon after the Planck time, Einstein's general relativity theory should be corrected to an effective quadratic theory. In this work we present the 3+1 decomposi…
The Poincare Conjecture and the Cosmological Constant
M. D. Maia
The concept of deformation of Riemannian geometry is reviewed, with applications to gravitation and cosmology. Starting with an analysis of the cosmological constant problem, it is…
On Special Re-quantization of a Black Hole
S. C. Ulhoa
Quantized expressions for the gravitational energy and momentum are derived from a linearized theory of teleparallel gravity. The derivation relies on a second-quantization procedu…
