Is Vacuum Quadratic Poincare Gauge Field Theory a Viable Gauge Theory ofGravitation

摘要

Some foundations of the vacuum QPGFT (Quadratic Poincare Gauge Field Theory) arediscussed, including the correspondence with general relativity, confinement, holonomy, Hamiltonian formalization, Birkoff theorem and the principles of minimal coupling and gauge invariance. It is established that the description of matter in terms of classical fields is illegitimate and that the QPGFT needs grading and extension to the gauge theory of the four dimensional real affine group of the metric affine theory. It is concluded that the vacuum QPGFT is not a viable microscopic gauge theory of gravitation.
