On the Asymptotics of Quantum Group Spinfoam Model

Understand

Recently a quantum group deformation of EPRL spinfoam model was proposed in arXiv:1012.4216 by one of the authors, and in arXiv:1012.4784 by Fairbairn and Meusburger.

• It is interesting to study the high spin asymptotics of the quantum group spinfoam model, to see if it gives the discrete Einstein gravity with cosmological constant as its semiclassical limit.
• In this article we propose a new technique, which can simplify the analysis of the high spin asymptotics for quantum group spinfoam vertex amplitude.
• This technique can generalize the spinfoam asymptotic analysis developed by Barrett, et al to quantum group spinfoam.
