In this study, we prove the existence and local uniqueness of radially symmetric solutions of nonlinear partial differential equations via a rigorous numerical method. We introduce the concepts of Banach spaces of geometrically decaying sequences and explore the domains of convergence of the Taylor and Chebyshev expansions. These notions constitute the basis for the Radii Polynomial Theorem on Banach spaces of infinite sequences, which is the main tool employed to obtain the proofs by using a combination of Taylor and Chebyshev coefficients of the solutions. We also introduce briefly the notions of interval analysis to justify the rigor of our computer-assisted results.

520 $a Dans cette etude, nous prouvons l'existence et l'unicite locale de solutions d'EDPs non lineaires et symetriques via une methode numerique. Nous introduisons des concepts sur les espaces de Banach de suites a decroissance geometrique et explorons les domaines de convergence des series de Taylor et de Chebyshev. Ces notions constituent les bases du Theoreme du Polynome de Rayons sur les espaces de Banach de suites infinies, qui sera l'outil principal pour obtenir les preuves en utilisant une combinaison de coefficients de Taylor et de Chebyshev. Nous introduisons egalement des notions de base sur l'analyse d'intervalle pour justifier la rigueur des resultats obtenus numeriquement.
