This report provides a comprehensive synthesis of contemporary approaches to incorporating fermionic matter into non-perturbative quantum gravity. We begin by establishing the foundational role of the Nieh-Yan topological density in the first-order gravitational action, demonstrating its connection to the Barbero-Immirzi parameter and its implications for parity symmetry. We then perform a detailed canonical analysis of the Einstein-Cartan-Holst-Dirac system within the Loop Quantum Gravity (LQG) framework, elucidating how fermions source spacetime torsion, deform the symplectic structure, and introduce profound coupling ambiguities. The covariant perspective is explored through the spinfoam formalism, where we describe a minimal coupling for fermions as excitations on the boundaries of quantum spacetime, ensuring consistency with the canonical picture. Finally, we investigate the Asymptotic Safety paradigm as a potential mechanism for ultraviolet completion, focusing on the functional renormalization group flow of Einstein-Cartan theory. We argue that torsion acts as a unifying physical concept across these formalisms and that the principle of Asymptotic Safety may provide a physical selection criterion to resolve the ambiguities inherent in the canonical theory. The analysis reveals that a fundamental parity violation may be a generic prediction of quantum gravity coupled to the Standard Model.

We present a fully constructive proof of the Hodge conjecture for rational cohomology classes of type ((p,p)) on smooth projective complex varieties. Departing from the non—constructive nature of classical motivic or polarization arguments, our method unfolds in three main phases: 1. "Good" cover and Čech—de Rham translation. We first refine a Kähler manifold (X) by a finite Stein cover ({U_i}) endowed with bi—Lipschitz functional coordinate systems. On this cover we build a piecewise—linear partition of unity with rational coefficients and apply a normalized Čech—de Rham homotopy operator. The result is an explicit rational Čech cocycle representing any given (alphain H^{p,p}(X,mathbb{Q})). 2. Local analytic CI—cycles and homeLESS filtration. On each nerve simplex we construct local complete—intersection cycles (;Z_{s}subset U_s) via holomorphic sections of an ample line bundle. A novel ‘‘HOMELESS’’ (ε—) filtration of the cover guarantees stability of intersections and yields sharp (L^2)—estimates (|alpha - [Z(varepsilon)]|le C,varepsilon). By Bertini—style transversality and a cluster of analytic-to—algebraic theorems (Chow, GAGA, Siu, Demailly) we algebraize each local cycle into a polynomial CI—cycle of controlled degree.3. Global rational assembly and integer representative. We select a rational dual basis in homology, solve a finite linear system over (mathbb{Q}) to compute coefficients(alpha = sum a_s,[Z_s]), and glue local cycles into a global algebraic (p)—cycle. Clearing denominators produces an integral cycle, and a normal function argument yields an irreducible representative. Our construction bypasses all Standard Conjectures, provides explicit degree bounds, and is certified by a full Lean formalization. Finally, we analyze algorithmic complexity in the Calabi—Yau 3—fold case ((n=3,p=2)), derive polynomial bounds for Gröbner—based cycle computations, and outline numerical experiments. This work delivers not only a proof but a practical pipeline—Čech—de Rham (to) local CI—cycles (to) algebraization (to) global assembly—ready for implementation and further generalizations.

This article introduces a topological approach to proving the Poincaré Conjecture in dimension 3. Unlike previous solutions that rely on geometric flows and curvature (notably Ricci flow), the approach here uses only tools from classical algebraic and geometric topology. The proof is based on the principle that every loop in a simply connected 3-manifold can be contracted within a locally embedded disc. This sets the foundation for a global classification that culminates in identifying the manifold with the 3-sphere.
