Description
Loop quantum gravity is an approach to defining a theory of quantum gravity in a background-independent and non-perturbative way. While this results in a very appealing mathematical and geometrical framework, in which space and time become naturally discretized, there are several open questions, such as how to make contact with particle physics. In particular, the issue of renormalization is still not well understood in this background-independent way. In this talk I will go over the basic priniples of LQG, and recount some of its features. In the second part, I will delve into modern research in the field, including recent results about the RG flow of the amplitudes of the theory.
