To further motivate and promote the research of numerical relativity, gravitational wave physics and relevant fields in China, we are going to organize a spring school on numerical relativity and grav...
Relativistic analogue of the D'Alembert principle of virtual displacements and the effective actions for the spherically-symmetric charged dust shell in General Relativity
Relativistic analogue D'Alembert principle of virtual displacements effective actions spherically-symmetric charged dust shell General Relativity
2010/12/20
A simple and direct derivation of the variational principle and effective actions for a spherical charged dust shell in general relativity is offered. This principle is based on the relativistic versi...
We consider the motion of tachyons (faster-than-light particles)in the framework of General Relativity. An important feature is the large contribution of low energy tachyons to the energy-momentum ten...

Epicycles Poincaré Resonances General Relativity
2010/12/20
The method of geodesic deviations provides analytic approximations to geodesics in arbitrary background space-times. As such the method is a useful tool in many practical situations. In this note we p...

Aureliano de Mira Fernandes, born in 1884 in Portugal, was professor of Differential and Integral Calculus and Rational Mechanics, at Instituto Superior T´ecnico,from its foundation in 1911, onw...
Inversion of hyperelliptic integrals of arbitrary genus with application to particle motion in General Relativity
Inversion of hyperelliptic integrals arbitrary genus application particle motion General Relativity
2010/12/20
The description of many dynamical problems like the particle motion in higher dimensional
spherically and axially symmetric space-times is reduced to the inversion of a holomorphic hyperelliptic inte...

LRS Bianchi type II models Cosmological constant
2010/12/20
Locally rotationally symmetric (L.R.S.) Bianchi type II stiff fluid cos-mological model is investigated. To get the deterministic model of the universe, we have assumed a condition A = Bm between metr...

Stationary Axisymmetric Neutron Stars Meridional Circulation General Relativity
2010/12/20
We present the first stationary, axisymmetric neutron star models with meridional circulation in general relativity. For that purpose, we developed GRNS, a new code based on a fixed point iteration.

Complementarity of Kinematics Geometry General Relativity Theory
2010/12/20
Relations between kinematics, geometry and law of reference frame motion are considered. We show, that kinematical tensors define geometry up to a space functiona arbitrariness when integrability cond...
