Abstract:
This article is devoted to the complete proof of the main theorem in the author's paper of 2004 showing that the Fourier–Laplace transform of an irreducible regular differential system on the Riemann sphere underlies, at finite distance, a polarizable regular twistor $\mathcal D$-module.
Key words and phrases:flat bundle, harmonic metric, twistor $\mathcal D$-module, Fourier–Laplace transform.
