Spin Foam Introductory Texts

What are some good introductory texts on spin foams / LQG for someone specialized in SUSY / string models? I’m somewhat familiar with some of the literature (Topological Amodel and crystal melting / ...

Coordinate space of loops in loop quantum gravity

I have a basic and perhaps admittedly misguided question about the loops in LQG. Broadly speaking I think I understand the logic that lead to them, namely that working in the ADM formalism (using the ...

Is Loop Quantum Gravity related with loops?

I read this article on wikipedia on loops. And I wondered if the loops of loop quantum gravity have the algebraic structure of loops or it's just a coincidence.

Does a good path integral exist in Loop Quantum Gravity?

The Hamiltonian operator of Loop quantum gravity is a totally constraint system $$H = \int_\Sigma d^3x\ (N\mathcal{H}+N^a V_a+G)$$ Here, $\Sigma$ is a 3-dimensional hypersurface; a slice of ...

Good mathematical introduction to loop quantum gravity [duplicate]

All websites or papers I could find did only have a mathless introduction for laymen. Does anybody know where to find a precise and mathematical introduction to LQG, for example containing the "...

A brief description of a plausible and possible candidate for Quantum Gravity [closed]

I wanted to know the specifics(essence) of a particular theory that is present for quantum gravity (QG),and which seems to have the best potential. I am no expert on field theories and QG, cause ...

Number of free parameters in String Theory and LQG

In the Standard Model, we have these free parameters: 6 quark masses 6 lepton masses 3 coupling constants Higgs mass Higgs VEV 4 CKM parameters 4 PMNS parameters QCD vacuum angle That's 26 in total. ...
I'm reading the book Quantum Gravity by Carlo Rovelli. In page 107, he says that the evolution equation of the system can be cast into $f=0$, where $f$ is a map such that \$f: \mathcal{C}\times \Gamma \...
