It is widely accepted that the Feynman integral one of most promising methodologies for defining a generally covariant formulation nonperturbative interacting quantum field theories (QFTs) without fixed prearranged causal background. Recent literature suggests if spacetime metric not fixed, e.g. because it to be quantized along with other fields, may able avoid considering in original Lorentz s...
