Description
This monograph develops a unified interpretation of quantum many-body physics by embeddingthe path-integral formalism into the geometry of signature space. Beginning with canonical quantum field theory and the construction of path integrals for particles, bosons, fermions, and photons, the analysis proceeds toward a structural reinterpretation in which local amplitudes act askernel operators and partition functions define global field closures. Bose-Einstein condensation, superconductivity, and photon equilibrium are recast as distinct regimes of collective organizationwithin a common geometric framework. The General Theory of Signature Space (GTSS) is introduced as a meta-structure that captures theseregimes through parameters governing curvature, coherence, and fluctuation. In this formulation, the path integral ceases to be merely a computational technique and becomes a generator of fieldgeometry, linking microscopic dynamics to macroscopic phases through signature-dependent closure. The resulting framework extends beyond condensed matter physics, providing a general ontology of collective systems applicable to cognitive, social, and informational domains. The monograph demonstrates that quantum many-body theory already contains the seeds of auniversal field geometry; GTSS makes this structure explicit and operational.
