Pure connection action principle for general relativity
K Krasnov - Physical review letters, 2011 - APS
Physical review letters, 2011•APS
It has already been known for two decades that general relativity can be reformulated as a
certain gauge theory, so that the only dynamical field is an SO (3) connection and the
spacetime metric appears as a derived object. However, no simple action principle realizing
these ideas has been available. A new elegant action principle for such a “pure connection”
formulation of GR is described.
