Abstract: The UNIFIED HOLOGRAPHIC MASTER ACTION Bridging Four-Dimensional Bulk Gravity, Three-Dimensional Cutoff Dynamics, and Non-Hermitian Quantum Evolution Dr. Theodor Heutschi Independent Researcher Research framework connected to dS₄/CFT₃ and non-Hermitian T T̄ flows Date: 9. November 2026 AbstractThis note constructs a unified variational framework linking four-dimensional bulk gravity to a three-dimensional cutoff theory, while treating non-Hermitian boundary evolution as a constrained quantum sector. The central object is a bulk-plus-boundary action with the Gibbons–Hawking–York term, local counterterms, matter fields, and a finite-cutoff boundary deformation by a quadratic stress-tensor operator. The radial Hamilton–Jacobi equation supplies the precise bridge between the bulk canonical momentum and the boundary stress tensor.The construction is deliberately conservative. A local gravitational action does not, by itself, prove the existence of a positive metric operator for a non-Hermitian boundary Hamiltonian, nor does it imply a universal numerical coefficient in a four-dimensional cosmological scaling law. Pseudo-Hermiticity, spectral reality, exceptional-point avoidance, and higher-derivative early-warning diagnostics are therefore stated as additional conditions on the quantum theory, not falsely presented as automatic Euler–Lagrange consequences. The result is a coherent master action and a derivation of its classical and boundary equations, together with a clear list of what remains model-dependent. 1. Scope, conventions, and logical statusWe work in four bulk dimensions with Lorentzian signature (−,+,+,+), and a timelike three-dimensional cutoff hypersurface Σ_c with induced metric γ_ij. The bulk Newton constant is G₄ and κ₄² ≡ 8πG₄. Coordinates have dimensions of length, ℏ = c = 1, and the action is dimensionless.[G₄] = L², [Λ₄] = L⁻², [Tᵢⱼ] = L⁻³, [TᵢⱼTᵢⱼ] = L⁻⁶. (1.1)Building upon the methodological groundwork and the 𝑇𝑇̅-deformation programme developed in earlier frameworks (Heutschi, 2026a,b), this note constructs a unified variational framework linking four-dimensional bulk gravity to a three-dimensional cutoff theory, while treating non-Hermitian boundary evolution as a constrained quantum sector.The phrase “T T̄-deformation” has a canonical meaning in two dimensions. In three dimensions there is no unique universally accepted determinant operator with all the special properties of the 2D T T̄ composite. We therefore define an explicit quadratic stress-tensor deformation and keep its normalization parameter free. This is essential for dimensional and mathematical honesty.Three levels of statements are distinguished throughout: (i) identities following from the displayed action and variational principle; (ii) conditional statements requiring a specified boundary quantum theory and spectrum; and (iii) phenomenological diagnostics that require numerical or experimental calibration.
