黎曼流形上的变分样条及其在integral geometry中的应用

Variational splines on Riemannian manifolds with applications to integral geometry

Isaac Pesenson

摘要:

本文将经典的变分插值样条理论推广到紧致黎曼流形的情形。我们的考虑包括特别是这样的问题,作为插值的功能,其价值观的离散集的点和插值的价值观的积分超过一个家庭的子流形。证明了黎曼流形上插值变分样条的存在唯一性。这种样条的最佳性能。给出了变分样条函数的Laplace-Beltrami算子本征函数的显式表达式,并证明了在离散点集上插值时,变分样条收敛于流形上的一个$C^{k}$模函数.给出了这些结果在单位球面上的半球变换和Radon变换中的应用。

英文摘要:

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.
