Geometry Transition in Spinfoams
Marios Christodoulou, Fabio D'Ambrosio, Charalampos Theofilis
We show how the fixed-spin asymptotics of the EPRL model can be used to perform the spin-sum for spin foam amplitudes defined on fixed two-complexes without interior faces and cont…

Hypersurface-deformation algebroids and effective space-time models
Martin Bojowald, Suddhasattwa Brahma, Umut Buyukcam +1
In canonical gravity, covariance is implemented by brackets of hypersurface-deformation generators forming a Lie algebroid. Lie algebroid morphisms therefore allow one to relate di…
