Mapping and Embedding of Two Metrics Associated with Dark Matter, Dark Energy, and Ordinary Matter
A. C. V. V. de Siqueira
In this paper we build a mapping between two different metrics and embed them in a flat manifold. One of the metrics represents the ordinary matter, and the other describes the dar…

A Possible Origin of Dark Matter, Dark Energy, and Particle-Antiparticle Asymmetry
A. C. V. V. de Siqueira
In this paper we present a possible origin of dark matter and dark energy from a solution of the Einstein's equation to a primordial universe, which was presented in a previous pap…

Exact Solutions of Einstein Equations
A. C. V. V. de Siqueira
We use a metric of the type Friedmann-Robertson-Walker to obtain new exact solutions of Einstein equations for a scalar and massive field. The solutions have a permanent or transit…
