Goldstone's Theorem and Hamiltonian of Multi-galileon Modified Gravity
Goldstone's Theorem Hamiltonian of Multi-galileon Modified Gravity
2010/12/21
The galileon model was recently proposed to locally describe a class of modi ed gravity theories,including the braneworld DGP model. We discuss spontaneous symmetry breaking of the self-accelerating b...

Cosmological consequences Modified Gravity
2010/12/20
As an alternative to the LCDM concordance model, Scalar-Tensor-Vector Modified Gravity (MOG) theory reproduces key cosmological observations without postulating the presence of an exotic dark matter c...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
2010/12/20
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structur and cosmo...
In the context of $f(R)$ gravity theories, the issue of finding static and spherically symmetric black hole solutions is addressed. Two approaches to study the existence of such solutions are consider...
