This work presents a comprehensive mathematical revision and formalization of the theoretical framework of Quarkbase Cosmology, with the aim of rigorously assessing its compatibility with relativistic invariance. Building upon the foundations established in previous publications—where a fundamental underlying medium composed of elementary entities called quarkbases was proposed—this study develops a fully covariant treatment of the associated field, from the minimal Lagrangian to the observable consequences on the propagation of perturbations.The simplest action reproducing the field equation previously postulated by the author is derived, and the corresponding energy–momentum tensor is calculated, allowing an explicit evaluation of local conservation and energy exchange between field and sources. The static equation for a point-like source is then solved, yielding a Yukawa-type potential, and a closed analytical expression for the field energy is obtained. It is shown that this energy diverges in the point limit a → 0, and that natural regularization requires the introduction of an effective quarkbase radius or volume.On this basis, the propagation of waves in the quarkbase medium, the correction to the effective refractive index, and the possible Lorentz-violating effects induced by isotropic or anisotropic couplings are analyzed. Explicit expressions for the relative deviation of the phase velocity (Δc/c) are obtained and compared with current experimental constraints (GRB/Fermi and optical resonator tests).The main result is that, under conditions of homogeneity and weak coupling, Quarkbase Cosmology preserves relativistic invariance within current experimental bounds. Moreover, quantitative limits are established for the parameters α, nq, λ, and ϵ, and a covariant Lagrangian framework is proposed that allows the theory to be extended to future gravitational or cosmological contexts.Reconfirmación de la invarianza relativista de la Teoría del Quarkbase: Análisis matemático detalladoEl presente trabajo constituye una revisión y formalización matemática del marco teórico de la Cosmología del Quarkbase, con el objetivo de evaluar rigurosamente su compatibilidad con la invarianza relativista. Partiendo de los fundamentos planteados en publicaciones anteriores —donde se propuso un medio subyacente constituido por entidades elementales denominadas quarkbases—, aquí se desarrolla un tratamiento covariante completo del campo asociado, desde el lagrangiano mínimo hasta las consecuencias observacionales sobre la propagación de perturbaciones.Se deriva la acción más simple que reproduce la ecuación de campo postulada por el autor y se calcula el tensor energía–momento correspondiente, lo que permite evaluar la conservación local y el intercambio de energía entre campo y fuentes. A continuación, se resuelve la ecuación estática para una fuente puntual, obteniendo la solución tipo Yukawa, y se realiza un cálculo cerrado de la energía de campo, mostrando que ésta diverge en el límite puntual a → 0 y que la regularización natural requiere la introducción de un radio o volumen efectivo de quarkbase.Sobre esta base, se analizan las condiciones de propagación de ondas en el medio quarkbase, la corrección al índice de refracción y las posibles violaciones de Lorentz inducidas por acoplamientos isotrópicos o anisotrópicos. Se obtienen expresiones explícitas para la desviación relativa de la velocidad de fase (Δc/c) y se comparan con los límites experimentales actuales (GRB/Fermi, resonadores ópticos).El resultado principal es que, bajo condiciones de homogeneidad y acoplamiento débil, la cosmología del Quarkbase preserva la invarianza relativista dentro de los márgenes experimentales. Además, se establecen límites cuantitativos para los parámetros α, nq, λ, and ϵ, y se propone un marco lagrangiano que permite incorporar la teoría a contextos gravitacionales o cosmológicos futuros.
