Orthoprojectors on perturbations of splines spaces
Karen Keryan, Markus Passenbrunner
We show that -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 .
Unconditionality of Periodic Orthonormal Spline Systems in
K. Keryan, M. Passenbrunner
Given any natural number and any dense point sequence on the torus , we prove that the corresponding periodic orthonormal spline system of order is an un…
Unconditionality of orthogonal spline systems in
Gegham Gevorkyan, Anna Kamont, Karen Keryan +1
We give a simple geometric characterization of knot sequences for which the corresponding orthonormal spline system of arbitrary order is an unconditional basis in the atomic H…
