What is the idea behind Group Field Theory by Oriti?

[ensabah6]

In plain English, what is the idea behind Group Field Theory by Oriti? How does this involve LQG, SF, and CDT?

There is not a popular exposition on the subject nor even a wiki article.


thanks

As it's told by the name, it's quantum field theory where the variables are group elements. It could be thought as a generalization of spinfoam for whatever group (spinfoam is constructed on SO(4) ) and I think the best reference could be the article by Daniele
