报告摘要：We give the detail analysis of the asymptotic behavior of EPRL spin foam model. The asymptotics of spin foam amplitude is totally controlled by its critical configurations. Using critical configurations we can reconstruct the classical geometry. We show that spin foam goes back to Palatini-Regge gravity when we take large spin limit.
