Piecewise linear interpolation via kernels

Toni Karvonen, Gabriele Santin, Tizian Wenzel

We consider piecewise linear interpolation from the perspective of kernel interpolation and quadrature. If the Sobolev space $W_{2}^{1} (0, 1)$ is equipped with a suitable inner product…

General superconvergence for kernel-based approximation

Toni Karvonen, Gabriele Santin, Tizian Wenzel

Kernel interpolation is a fundamental technique for approximating functions from scattered data, with a well-understood convergence theory when interpolating elements of a reproduc…
