Pre-big bang collapsing universe from modern Kaluza-Klein theory of gravity
Pre-big bang collapsing universe modern Kaluza-Klein theory gravity
2011/10/18
We study the collapse of the universe described by a scalar field spherically symmetric collapse of a system described by a massless scalar field from a 5D Riemann-flat canonical metric, on which we m...
A cyclic cosmological model based on the f(ρ) modified theory of gravity
modified gravity, dark energy, cosmology, nonsingular,cosmological constant
2011/8/26
We consider FLRW cosmological models for perfect fluid (with rho as the energy density) in the frame work of the f(rho) modified theory of gravity [V. N. Tunyak, Russ. Phys. J. 21, 1221 (1978); J. R. ...
We discuss aspects of global and gauged symmetries in quantum field theory and quantum gravity, focusing on discrete gauge symmetries. An effective Lagrangian description of $\Z_p$ gauge theories sho...
Nonrelativistic general covariant theory of gravity with a running constant $\lambda$
Nonrelativistic general covariant theory gravity running constant
2010/12/23
In this paper, we investigate three important issues: ghost, stability and strong coupling, in the Horava-Melby-Thompson (HMT) setup of the Horava-Lifshitz (HL) theory with $\lambda \not= 1$. We firs...

Nonrelativistic general covariant theory of gravity constant $\lambda$
2010/12/21
In this paper, we investigate three important issues: ghost, stability and strong coupling, in
the Horava-Melby-Thompson (HMT) setup of the Horava-Lifshitz (HL) theory with 6= 1. We
first develop ...
Quantum theory, noncommutative gravity, and the cosmological constant problem
Quantum theory noncommutative gravity cosmological constant problem
2010/4/13
The cosmological constant problem is principally concerned with trying to understand how the zero-point energy of quantum fields contributes to gravity. Here we take the approach that by addressing a ...
On the Nonlinear Theory for Gravity Waves on the Ocean's Surface. Part II：Interpretation and Applications
Nonlinear Theory Gravity Waves Ocean's Surface Interpretation
2009/3/7
In a previous paper (Weber and Barrick, 1977), a generalization of Stokes’ perturbational technique permitted us to obtain solutions to higher orders for gravity-wave parameters for an arbitrary, two-...

Nonlinear Theory Ocean's Surface Gravity Waves
2009/3/7
A general hydrodynamic solution is derived for arbitrary gravity-wave fields on the ocean surface by extending Stokes' (1847) original perturbational analysis. The solution to the nonlinear equations ...
