Algebraic Structures, Physics and Geometry from a Unified Field Theoretical Framework
(Springer, 2015-10)
Starting from a Unified Field Theory (UFT) proposed previously by the author, the possible fermionic representations arising from the same spacetime are considered from the algebraic and geometrical viewpoint. We specifically ...
Towards unified spinor fields: confinement of gravitons on a dS background
(National Research Council Canada-NRC Research Press, 2019-02)
We propose a unified theory for spinor fields on extended Weyl manifolds taking into account self-interactions to obtain the relativistic dynamics on a general curved Riemannian background as a continuation of the relativistic ...
Gravitons emission during pre-inflation from unified spinor fields
(Springer, 2018-12)
We obtain the equation that describe the conditions of quantization for neutral massless bosons on an arbitrary curved space-time, obtained using a particular theoretical formalism developed in a previous work (M.R.A. ...
Gravitation and Electromagnetism as Geometrical Objects of a Riemann-Cartan Spacetime Structure
(Springer Basel AgBaselSuíça, 2012)
Comments on Unified dark energy and dark matter from a scalar field different from quintessence
(Bentham Science Publishers Ltd., 2011-10)
In a recent paper by C. Gao, M. Kunz, A. Liddle and D. Parkinson [1] the unification of dark matter and dark energy was explored within a theory, which they say is not of the Lagrangian type, containing a scalar field. ...
Non-Riemannian geometry, Born–Infeld models and trace free gravitational equations
(Elsevier B.V., 2017-08)
Non-Riemannian generalization of the standard Born–Infeld (BI) Lagrangian is introduced and analyzed from a theory of gravitation with dynamical torsion field. The field equations derived from the proposed action lead to ...
