Abstract (EN):
We study some issues related to the notion of generalized holonomies, providing a rigorous
mathematical framework where to discuss early heuristic ideas from the physics literature,
mainly due to R. Gambini and its colaborators, who have tryed to formulate an “Extended
Loop Representation” of Quantum Gravity in Ashtekar variables. We also define a BACH
(Baker-Campbell-Hausdorff) series for the formal generalized holonomy and prove its
convergence in some particular cases. Finally we discuss the issue of covariance of generalized
holonomies, and prove the covariance for nilpotent connections.
