The Cosmological Constant in the Quantum Multiverse
Cosmological Constant Quantum Multiverse
2011/10/17
Recently, a new framework for describing the multiverse has been proposed which is based on the principles of quantum mechanics. The framework allows for well-defined predictions, both regarding globa...
Inflation and the cosmological constant

2011/10/14
A particular compensation-type solution of the main cosmological constant problem has been proposed recently, with two massless vector fields dynamically canceling an arbitrary cosmological constant \...
The Poincare Conjecture and the Cosmological Constant

2011/10/17
The concept of deformation of Riemannian geometry is reviewed, with applications to gravitation and cosmology. Starting with an analysis of the cosmological constant problem, it is shown that space-ti...
Notes on the Quantization of FRW Model in the Presence of a Cosmological Constant and Radiation
FRW Model a Cosmological Constant
2010/10/18
In the present work, we use the formalism of quantum general relativity in order to quantize a Friedmann-Robertson-Walker model in the presence of a negative cosmological constant and radiation. The m...
Neutrino Mixing as a Source for Cosmological Constant
Neutrino Mixing Cosmological Constant
2010/10/14
We report on recent results showing that neutrino mixing may lead to a non-zero contribution to the cosmological constant. This contribution is of a completely different nature with respect to the usu...
