Goldstone's Theorem and Hamiltonian of Multi-galileon Modified Gravity
Goldstone's Theorem Hamiltonian of Multi-galileon Modified Gravity
2010/11/16
The galileon model was recently proposed to locally describe a class of modied gravity theories,including the braneworld DGP model. We discuss spontaneous symmetry breaking of the self-accelerating b...
A Map for a Group of Resonant Cases in a Quartic Galactic Hamiltonian
elliptical-orbits-regular and chaotic motion maps Hamiltonian stability
2009/5/20
We present a map for the study of resonant motion in a potential
made up of two harmonic oscillators with quartic perturbing terms.
This potential can be considered to describe motion in the central...
