1+1 or 2+1. My focus is more on simplicity (i.e. manageable examples of loop technology) rather than a particular spacetime. If a toroidal space would make everything more simple then I'd be happy, if it's more a 2D lattice I'd consider that.
Maybe I could rephrase it as: is there a toy-model...
I'm looking for some simple articles on 2D physics, Wilson loops, loop variables and similar. The purpose is to gain insights in LQG using lower dimensions.
Thanks for your help
