Noether symmetry for Gauss-Bonnet dilatonic gravity
Noether symmetry Gauss-Bonnet dilatonic
<
2011/9/27
Noether symmetry for Gauss-Bonnet-Dilatonic interaction exists for a constant dilatonic scalar potential and a linear functional dependence of the coupling parameter on the scalar field. The symmetry ...
Noether Gauge Symmetry Approach in f(R) Gravity
f(R) gravity cosmology Noether symmetries

Abstract: We discuss the f(R) gravity model in which the origin of dark energy is identified as a modification of gravity. The Noether symmetry with gauge term is investigated for the f(R) cosmologica...
Electroweak Baryogenesis and Dark Matter with an approximate R-symmetry
Electroweak Baryogenesis Dark Matter with approximate R-symmetry

2011/10/18
It is well known that R-symmetric models dramatically alleviate the SUSY flavor and CP problems. We study particular modifications of existing R-symmetric models which share the solution to the above ...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity

We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
A new multi-dimensional general relativistic neutrino hydrodynamics code for core-collapse supernovae. I. Method and code tests in spherical symmetry

We present a new general relativistic (GR) code for hydrodynamic supernova simulations with neutrino transport in spherical and azimuthal symmetry (1D/2D). The code is a combination of the CoCoNuT hyd...

ON ORBITS FOR A PARTICULAR CASE OF AXIAL SYMMETRY
Galaxy: kinematics and dynamics Miyamoto and Nagai
<
2010/10/29
A particular case of steady state and axial symmetry -the potential formula proposed by Miyamoto and Nagai - is studied. A number of orbits of a bound test particle is determined numerically, with bot...
A particular case of steady state and spherical symmetry - the so-
called logarithmic potential introduced as the ¯rst approximation for dark coronae
of galaxies - is studied. Both time and ang...
