The graphical calculus method is generalized to study the relation between covariant and canonical dynamics of loop quantum gravity. On one hand, a derivation partition function Euclidean Engle-Pereira-Rovelli-Livine (EPRL) spin-foam model presented. other action Hamiltonian constraint operator on certain spin network states calculated by method. It turns out that EPRL can provide rigging map s...
