Bianca Dittrich, Erik Schnetter, Cameron J. Seth +1
Simplicity constraints play a crucial role in the construction of spin foam models, yet their effective behaviour on larger scales is scarcely explored. In this article we introduc…

Discretization independence implies non-locality in 4D discrete quantum gravity
Bianca Dittrich, Wojciech Kaminski, Sebastian Steinhaus
The 4D Regge action is invariant under 5--1 and 4--2 Pachner moves, which define a subset of (local) changes of the triangulation. Given this fact one might hope to find a local pa…
