On the 'volume simplicity' (and the ways towards it)
I recapitulate the status of the volume part of simplicity constraints in the EPRL-KKL model, and highlight the tension with their implementation (evidenced by non-geometric configurations in the asymptotics). I outline, at the level of the classical theory, the two main routes towards resolving this issue - in the quadratic or linear setting, respectively.
