[1407.2909] Linking shape dynamics and loop quantum gravity

[1407.2909] Linking shape dynamics and loop quantum gravity:

"Shape dynamics is a reformulation of general relativity, locally equivalent to Einstein's theory, in which the refoliation invariance of the older theory is traded for local scale invariance. Shape dynamics is here derived in a formulation related to the Ashtekar variables by beginning with a modification of the Plebanski action. The constraints of shape dynamics and their algebra are reproduced in terms of these new variables."
