Spectral Gap Selection of Lorentzian Signature from Observer Fisher Information Geometry
Abstract
Demonstrates that sparse Fisher information matrices for Ising-type models preferentially select Lorentzian signature via a spectral gap mechanism. Proves W(q=1) > W(q>=2) for sparse matrices with explicit stability bounds.
