Abstract
We present an error bound for a least squares version of the kernel based meshless finite difference method for elliptic differential equations on smooth compact manifolds of arbitrary dimension without boundary. In particular, we obtain sufficient conditions for the convergence of this method. Numerical examples are provided for the equation -Δ(M) u+u = f on the 2- and 3-spheres, where Δ(M) is the Laplace-Beltrami operator.Link to publications or other datasets
