Overview and Outlook
The coefficients of the expansion constitute the “loop representation”, which had been studied for Yang–Mills theories by Gambini and Trias in the 80’s and was introduced into the gravitational context by Rovelli and Smolin .
Lorentz violations in canonical quantum gravity
Such representation was first proposed for Yang–Mills theory by Gambini and Trias and for general relativity in terms of the new variables by Rovelli and Smolin . A caveat is that the basis provided by Wilson loops is really an overcomplete basis.
Canonical quantization of general relativity: the last 18 years in a nutshell
This technique had been used in the context of Yang –Mills theories by Gambini and Trias [9 ].

Here TriA is the category of triangles in A and morphisms as in (2.1).

For comparison, x dependence of the N ´eel temperature TN (x) in the 3D XY model obtained by the MC method and that in 3D Heisenberg model by the classical CE one are presented by filled tria ngles and dotted line, respectively.
Dilution effect in correlated electron system with orbital degeneracy
The action of the operators that represent the loop variables (2) and (4) are then defined by their action on the bra states: < γ | ˆT [α] =< α ∪ γ | 3As has been emphasized by Gambini and Trias and their coworkers, the space of these equivalence classes of loops actually forms a group.
What can we learn from the study of non-perturbative quantum general relativity?
The loop representation actually first appeared in a quantization of the free Maxwell field given by Gambini and Trias in 1981 .
What can we learn from the study of non-perturbative quantum general relativity?
This approach was pioneered in Yang–Mills theories by Gambini and Trias [6,7] and was applied in gravity by Rovelli and Smolin .
Canonical quantum gravity with new variables and loops: a report
This representation had been studied by Gambini and Trias in the Yang–Mills context in the early eighties with some success, including lattice gauge theory calculations .
