Inflation from Covariant Signature Change: A Geometric Mechanism
A covariant signature change from Euclidean to Lorentzian geometry on a curvature-regular hypersurface generates inflation via an effective geometric stress tensor, with duration set by the interpolator slope relative to extrinsic and spatial curvatures.
