We extend the classical theory of variational interpolating splines to the\ncase of compact Riemannian manifolds. Our consideration includes in particular\nsuch problems as interpolation of a function by its values on a discrete set of\npoints and interpolation by values of integrals over a family of submanifolds.\nThe existence and uniqueness of interpolating variational spline on a\nRiemannian manifold is proven. Optimal properties of such splines are shown.\nThe explicit formulas of variational splines in terms of the eigen functions of\nLaplace-Beltrami operator are found. It is also shown that in the case of\ninterpolation on discrete sets of points variational splines converge to a\nfunction in Ck norms on manifolds. Applications of these results to the\nhemispherical and Radon transforms on the unit sphere are given.\n
