The framework of canonical quantization of quantum field is given by Lagrangian (not Lagrangian density) formulation to avoid the problem of transfer physical quantities from 4–dimensional space–time to 3–dimensional position space (3–dimensional hypersurface with normal vector dt).
Keywords: Canonical quantization; Yang-Mills theory in curved space-time
