Numerical solutions to Einstein's equation are constructed on compact non-orientable spatial slices for simple cosmological models with varying curvatures, including locally homogeneous and inhomogeneous examples, to test the methods and code.
If φ > 0 and ˜R >0 this integral can vanish only if K 2 − 3Λ < 0
