The Topological Mechanism of Cosmic Inflation: Geometric Unknotting of the Gravitational Spin Tensor

Standard cosmological models postulate a scalar "inflaton" field to drive the exponential expansion of the early universe. In this monograph, we propose a pure geometric mechanism for Cosmic Inflation based on Topological Quantum Chromodynamics (Topological QCD). We hypothesize that the pre-inflationary vacuum was a singularity of maximal topological entanglement within the Gravitational Spin Polarization Tensor $\Pi_{ab}$. Inflation was triggered by a rapid phase transition—a topological unknotting—where the release of geometric frustration drove the exponential expansion of the metric tensor. The modified Lichnerowicz identity explains the generation of primordial density fluctuations directly from the residual Borromean linkages, removing the need for ad hoc scalar fields.
