Note on flat foliations of spherically symmetric spacetimes
arXiv:gr-qc/0110068 · doi:10.1103/PhysRevD.65.027501
Abstract
It is known that spherically symmetric spacetimes admit flat spacelike foliations. We point out a simple method of seeing this result via the Hamiltonian constraints of general relativity. The method yields explicit formulas for the extrinsic curvatures of the slicings.
