We consider the problem of the optimal recovery of harmonic functions in the ball from inaccurate information on the Radon transform. Presented are the error of the optimal recovery and the set of optimal methods for which this error is attained.
Keywords: optimal recovery, harmonic function, Hardy space, spherical harmonic, Lagrange function, Bessel function.
Mots-clés : Radon transform, Gegenbauer polynomial
