Spinfoam Cosmology | |||||

|
Abstract |
In Loop Quantum Gravity it is possible to compute transition amplitudes between cosmological states. In the semiclassical limit, these has been proven to lead to Friedmann dynamics, also for non trivial case such as de Sitter space. I will review this approach to cosmology, discussing opportunities and open issues. |

Title |
Spinfoam for cosmologists | |||||
| Co-authors | ||||||||
|
Abstract |
The covariant dynamics of LQG (spinfoam) can provide new tools for doing cosmology. I review the basic ingredients of Spinfoam Cosmology, such as the graph truncation, coherent states and the vertex expansion, and I present some open directions in order to build cosmological models. |
