We consider the optimal recovery problem for the solution of the Dirichlet problem for the Laplace equation in the unit $d$-dimensional ball on a sphere of radius $\rho$ from a finite collection of inaccurately specified Fourier coefficients of the solution on a sphere of radius $r$, $0$. The methods are required to be exact on certain subspaces of spherical harmonics.
Keywords: optimal recovery, Dirichlet problem, spherical harmonics.
Mots-clés : Laplace equation
