New methods for quasi-interpolation approximations: resolution of odd-degree singularities
Martin Buhmann, Janin Jäger, Joaquín Jódar +1
In this paper, we study functional approximations where we choose the so-called radial basis function method and more specifically, quasi-interpolation. From the various available…

Strictly positive definite kernels on compact Riemannian manifolds
Jean Carlo Guella, Janin Jäger
The paper studies strictly positive definite kernels on compact Riemannian manifolds. We state new conditions to ensure strict positive definiteness for general kernels and kernels…

-summability and Fourier series of B-splines with respect to their knots
Martin Buhmann, Janin Jäger, Yuan Xu
We study the -summability of functions in the -dimensional torus and so-called -invariant functions. Those are functions on the torus whose Fourie…
