Math. 33 (2004), no. 3, 548-572", "categories": [ "math.FA" ], "abstract": "We extend the classical theory of variational interpolating splines to the case of compact Riemannian manifolds. Our consideration includes in particular such problems as interpolation of a function by its values on a discrete set of points and interpolation by values of integrals over a family of submanifolds. The existence and uniqueness of interpolating variational spline on a Riemannian manifold is proven. Optimal properties of such splines are shown. The explicit formulas of variational splines in terms of the eigen functions of Laplace-Beltrami operator are found. It is also shown that in the case of interpolation on discrete sets of points variational splines converge to a function in $C^{k}$ norms on manifolds. Applications of these results to the hemispherical and Radon transforms on the unit sphere are given.", "revisions": [ { "version": "v1", "updated": "2011-04-09T14:13:55.000Z" } ], "analyses": { "keywords": [ "integral geometry", "applications", "discrete set", "points variational splines converge", "compact riemannian manifolds" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1104.1709P" } } }
