How to Approach Quantum Gravity – Background Independence in 1+1 Dimensions

چکیده
The application of quantum theory to gravity is beset with many technical and conceptual problems. After a short tour d’horizon of recent attempts to master those problems by the introduction of new approaches, we show that the aim, a background independent quantum theory of gravity, can be reached in a particular area, 2d dilaton quantum gravity, without any assumptions beyond standard quantum field theory.

We present some approaches to the perturbative analysis of the classical and quantum gravity. First we introduce a graphical representation for a global SO(n) tensor (∂)hαβ , which generally appears in the weak field expansion around the flat space: gμν = δμν+hμν . Making use of this representation, we explain 1) Generating function of graphs (Feynman diagram approach), 2) Adjacency matrix (Mat...

متن کاملTowards a Background Independent Quantum Gravity in Eight Dimensions
We start a program of background independent quantum gravity in eight dimensions. We begin by considering canonical gravity a la ”Kaluza-Klein” in D = d + 1 dimensions. We show that our canonical gravity approach can be applied to the case of self-dual gravity in four dimensions. Further, by using our previously proposed classical action of Ashtekar self-dual gravity formalism in eight dimensio...
متن کاملLectures on Loop Quantum Gravity
Quantum General Relativity (QGR), sometimes called Loop Quantum Gravity, has matured over the past fifteen years to a mathematically rigorous candidate quantum field theory of the gravitational field. The features that distinguish it from other quantum gravity theories are 1) background independence and 2) minimality of structures. Background independence means that this is a non-perturbative a...
