In this work, we apply the smooth deformation concept in order to obtain a modification of
Friedmann's equations. It is shown that the cosmic coincidence can be at least alleviated …

In this paper, we examine a static gravitational field with axial symmetry over probe particles
in the Solar system. Using the Weyl conformastatic solution as a model, we find a non …

In this paper, we construct the covariant or model independent induced Einstein–Yang–Mills
field equations on a four-dimensional brane embedded isometrically in an D-dimensional …

In this work, we examine the orbit equations originated from Zipoy's oblate metric.
Accordingly, the solution of Einstein's vacuum equations can be written as a linear …

In a quest to explain the small value of the today's cosmological constant, following the
approach introduced in Jalalzadeh and Rostami (2015), we show that the theoretical value …

Desde as observações de Bosma e Rubin na década de 1970, as curvas de rotação das
galaxias compõem parte central de um dos principais problemas em discussão na …

No presente trabalho, investigamos o movimento lento na Relatividade Geral (RG) sob ação
de um campo gravitacional arbitrário. Trata-se do uso de uma aproximação conhecida por …

Apesar dos modelos de Branas-mundo terem recebido atenção considerável nos últimos
anos por fornecerem várias opções à física contemporânea, seus mecanismos não são …

The cosmological constant problem is examined within the context of the covariant brane-
world gravity, based on Nash's embedding theorem for Riemannian geometries. We show …

The understanding of gravitational phenomena has been considered a fundamental
problem in modern Cosmology. Recent observations of the CMBR power spectrum in the 7 …
