Abstract: | We prove the existence at small μ of a unique solution of the system to be satisfied by the set of Borel transformed euclidean Green's functions of a Φ24 theory, μ being the Borel conjugate variable of the coupling λ. As a byproduct, a new proof of convergence of the Borel transformed perturbative series is obtained. |
