Orthoprojectors on perturbations of splines spaces

Karen Keryan, Markus Passenbrunner

We show that $L^{\infty}$ -norms of orthoprojectors on certain types of perturbations of spline spaces are bounded independently of the knot sequence. Explicit applications of this re…

Projection operators onto spaces of Chebyshev splines

Karen Keryan, Markus Passenbrunner

We prove that the Chebyshev spline orthoprojectors are uniformly bounded on $L^{\infty}$ .

Unconditionality of Periodic Orthonormal Spline Systems in $L^{p}$

K. Keryan, M. Passenbrunner

Given any natural number $k$ and any dense point sequence $(t_{n})$ on the torus $T$ , we prove that the corresponding periodic orthonormal spline system of order $k$ is an un…
