Abstract: The present paper has a twofold contribution: first, we intro- duce a new concept of Hardy spaces on a multidimensional complexified annular domain which is closely related to the annulus of the Klein-Di rac quadric important in Conformal Quantum Field Theory. Secondly, for functions in these Hardy spaces, we provide error estimate for the p oly- harmonic Gauß-Jacobi cubature formulas, which have been introduced in previous papers.
