Description
Hypercomplex General Relativity (HGR), also referred to as Relativité Générale Hypercomplexe (RGH) in French, is a unified theoretical framework...
This deposit gathers and documents the complete body of work related to Hypercomplex General Relativity (HGR), an extension of General Relativity developed by Laurent Besson.
HGR introduces an internal hypercomplex structure within the spacetime metric, allowing a reformulation of gravity that preserves local consistency and the standard relativistic limit while avoiding Ostrogradsky-type instabilities.
The present record synthesizes successive versions of the model, including the initial formulation (2015), a comprehensive theoretical update (2025), and recent additions addressing critical discussions.
In a cosmological context, the model leads to a holographic-like behavior characterized by a late-time geometric component compatible with current observational constraints from the Cosmic Microwave Background and large-scale structure data.
This deposit includes the Lagrangian formulation, the field equations, and numerical implementations based on a modified version of standard cosmology codes, and is released within an open science framework to ensure long-term accessibility, reproducibility, and citation.
Keywords: general relativity, modified gravity, hypercomplex geometry, cosmology, theoretical physics.
Objective
The goal of this development is to refine the internal structure of Hypercomplex General Relativity and determine whether quantization of the internal sector is physically necessary or conceptually supportive.
The previous classical formulation introduced a curvature-dependent threshold controlling local gravitational corrections. The present work reinterprets this threshold in terms of a canonical internal gauge structure.
1. Canonical Structure of the Internal Sector
The hypercomplex connection is modeled as a non-abelian gauge field. A full Hamiltonian analysis is performed, including:
-
3+1 decomposition,
-
identification of canonical variables,
-
Gauss constraint implementation,
-
well-defined phase space.
The non-commutative structure emerges from the symplectic form and canonical commutation relations, rather than being assumed.
This establishes that the internal RGH sector possesses a legitimate gauge-theoretic foundation.
2. Construction of a Gauge-Invariant Internal Observable
A scalar observable is constructed from quadratic electric-like and magnetic-like internal invariants.
This observable:
-
is locally gauge invariant,
-
is positive definite,
-
can be promoted to an operator,
-
controls the effective gravitational correction threshold.
The threshold becomes state-dependent via expectation values, introducing a statistical interpretation of rebound domains.
3. Semi-Classical Regime
In a semi-classical approximation, fluctuations of the internal observable modify the effective threshold.
This implies that:
-
internal quantum variance may broaden the population of rebound-triggering domains,
-
the mechanism admits a probabilistic interpretation at high curvature.
However, the core rebound mechanism does not rely strictly on quantization.
4. Internal Saturation Mechanism
A critical issue arises: without regulation, the internal scalar could grow unbounded at high curvature.
To ensure stability, a saturation function is introduced:
-
the internal response becomes bounded,
-
corrections remain finite,
-
ultraviolet divergence is avoided,
-
local activation remains possible.
This mechanism stabilizes the theory without requiring full quantum gravity.
5. Conceptual Status at the End of This Stage
Established:
-
Canonical internal gauge structure.
-
Well-defined observable controlling corrections.
-
Dynamically bounded internal response.
-
Stabilized domain-triggered rebound mechanism.
Not yet addressed:
-
Full quantization of gravity.
-
Complete cosmological perturbation analysis.
-
Weak-field post-Newtonian constraints.
Strategic Insight
Quantization of the internal sector provides micro-structural grounding and theoretical elegance.
However, the macroscopic consistency of RGH does not depend on full gravitational quantization. The saturation mechanism alone is sufficient to ensure stability and physical viability.
This stage transforms RGH from an intuitive hypercomplex extension into a symplectically structured, dynamically regulated gravitational framework.
Abstract (En)
This work presents an advanced development of Hypercomplex General Relativity (RGH), focusing on the internal non-abelian sector, its canonical structure, and the emergence of a dynamically bounded correction to gravitational dynamics.
The internal hypercomplex connection is treated as a genuine gauge sector with a well-defined symplectic structure. A canonical 3+1 decomposition is performed, leading to a consistent Hamiltonian formulation and Gauss constraint. Non-commutativity is not postulated but emerges naturally from the symplectic structure upon canonical quantization.
A key scalar internal observable, constructed from gauge-electric and gauge-magnetic invariants, is promoted to an operator. The effective gravitational threshold responsible for triggering RGH corrections becomes state-dependent through expectation values of this observable.
To prevent uncontrolled growth of internal corrections at high curvature, a saturation mechanism is introduced. The internal response becomes dynamically bounded while remaining locally active. This produces a stable rebond mechanism without requiring full quantization of gravity.
The result is a geometrically consistent framework in which:
-
internal structure is canonically defined,
-
the correction threshold is dynamically regulated,
-
local bounce domains remain finite,
-
ultraviolet instability is avoided through bounded internal response.
The quantization of the internal sector strengthens the micro-structural justification of the model but is not strictly required for its macroscopic consistency. RGH remains viable in a purely classical regime with nonlinear saturation.
This work clarifies the structural role of internal symplectic geometry and establishes a stable dynamical basis for domain-triggered gravitational corrections.
Abstract (French)
Ce travail présente une évolution avancée de la Relativité Générale Hypercomplexe (RGH), centrée sur la structuration du secteur interne non abélien, sa formulation canonique et l’introduction d’un mécanisme de saturation dynamique bornant les corrections gravitationnelles.
La connexion hypercomplexe interne est traitée comme un véritable secteur de jauge doté d’une structure symplectique bien définie. Une décomposition 3+1 permet d’établir une formulation hamiltonienne cohérente avec contrainte de Gauss. La non-commutativité n’est pas postulée a priori : elle émerge naturellement de la structure symplectique lors de la quantification canonique.
Un observable scalaire interne, construit à partir d’invariants quadratiques de type électrique et magnétique, est défini de manière rigoureuse. Promu au rang d’opérateur, il rend le seuil effectif des corrections gravitationnelles dépendant de l’état quantique via des valeurs moyennes.
Afin d’éviter toute croissance incontrôlée en régime de forte courbure, un mécanisme de saturation interne est introduit. La réponse interne devient dynamiquement bornée tout en restant localement active. Ce mécanisme stabilise les rebonds locaux sans nécessiter une quantification complète de la gravité.
Il en résulte un cadre géométriquement cohérent dans lequel :
-
la structure interne est canoniquement définie,
-
le seuil de correction est dynamiquement régulé,
-
les domaines rebondissants restent finis,
-
l’instabilité ultraviolette est évitée.
La quantification renforce la justification micro-structurelle du modèle mais n’est pas indispensable à sa cohérence macroscopique. La RGH demeure viable dans un régime purement classique doté d’une saturation non linéaire.
🔹 Résumé étendu (Description)
Objectif
Clarifier la structure interne de la RGH et déterminer si la quantification du secteur interne est physiquement nécessaire ou conceptuellement complémentaire.
Le modèle initial introduisait un seuil de correction dépendant de la courbure. Cette étape reformule ce seuil à partir d’une structure canonique interne rigoureuse.
1. Structure canonique du secteur interne
La connexion hypercomplexe est modélisée comme un champ de jauge non abélien.
Sont établis :
-
une décomposition 3+1,
-
l’identification des variables canoniques,
-
l’implémentation de la contrainte de Gauss,
-
un espace de phase bien défini.
La non-commutativité découle de la structure symplectique et des relations canoniques, et non d’un postulat ad hoc.
2. Observable interne invariant
Un scalaire interne est construit à partir d’invariants quadratiques de type électrique et magnétique.
Cet observable :
-
est localement invariant de jauge,
-
est positif,
-
peut être promu opérateur,
-
contrôle dynamiquement le seuil de correction gravitationnelle.
Le seuil devient dépendant de l’état via des valeurs moyennes, ouvrant une interprétation statistique des domaines rebondissants.
3. Régime semi-classique
En approximation semi-classique, les fluctuations de l’observable interne modifient le seuil effectif.
Cela implique que :
-
les fluctuations internes peuvent élargir la population de domaines déclenchant un rebond,
-
le mécanisme admet une lecture probabiliste en régime de forte courbure.
Toutefois, le rebond ne dépend pas strictement de la quantification.
4. Mécanisme de saturation interne
Sans régulation, l’observable interne pourrait croître sans borne en régime extrême.
Un mécanisme de saturation est introduit :
-
la réponse interne devient bornée,
-
les corrections restent finies,
-
les divergences ultraviolettes sont évitées,
-
l’activation locale reste possible.
La stabilité dynamique du modèle est ainsi assurée sans recourir à une gravité entièrement quantifiée.
5. État conceptuel actuel
Établi :
-
Structure canonique interne cohérente.
-
Observable invariant rigoureusement défini.
-
Seuil dynamique état-dépendant.
-
Saturation interne stabilisatrice.
-
Rebond local stabilisé.
Non encore traité :
-
Quantification complète du champ gravitationnel.
-
Analyse complète des perturbations cosmologiques.
-
Contraintes post-newtoniennes en champ faible.
Conclusion stratégique
La quantification du secteur interne apporte une justification micro-structurelle et une élégance formelle.
Cependant, la cohérence macroscopique de la RGH repose principalement sur la saturation non linéaire interne.
Cette étape marque le passage d’une extension hypercomplexe intuitive à un cadre géométrique symplectique structuré et dynamiquement régulé.
