On the value of the max-norm of the orthogonal projector onto splines with multiple knots
نویسنده
چکیده
The supremum over all knot sequences of the max-norm of the orthogonal spline projector is studied with respect to the order k of the splines and their smoothness. It is first bounded from below in terms of the max-norm of the orthogonal projector onto a space of incomplete polynomials. Then, for continuous and for differentiable splines, its order of growth is shown to be √ k.

Open questions around the spline orthoprojector
An open problem about the max-norm of the spline orthoprojector is formulated. It gives rise to several conjectures about the orthoprojectors onto some spaces of polynomials. We discuss in this note several open questions concerning the orthogonal projector onto spline spaces. The main advance on the subject has of course been Shadrin’s proof [9] of de Boor’s conjecture [1] that the max-norm of...
متن کاملA Construction of Bi orthogonal Functions to B splines with Multiple Knots
We present a construction of a re nable compactly supported vector of functions which is bi orthogonal to the vector of B splines of a given degree with multiple knots at the integers with prescribed multiplicity The construction is based on Hermite interpolatory subdivision schemes and on the relation between B splines and divided di erences The bi orthogonal vector of functions is shown to be...
متن کامل00 6 A counterexample concerning the L 2 - projector onto linear spline spaces
For the L2-orthogonal projection PV onto spaces of linear splines over simplicial partitions in polyhedral domains in IR, d > 1, we show that in contrast to the one-dimensional case, where ‖PV ‖L∞→L∞ ≤ 3 independently of the nature of the partition, in higher dimensions the L∞-norm of PV cannot be bounded uniformly with respect to the partition. This fact is folklore among specialists in finite...
متن کاملTENSION TRIGONOMETRIC SPLINES INTERPOLATION METHOD FOR SOLVING A LINEAR BOUNDARY VALUE PROBLEM
By using the trigonometric uniform splines of order 3 with a real tension factor, a numericalmethod is developed for solving a linear second order boundary value problems (2VBP) withDirichlet, Neumann and Cauchy types boundary conditions. The moment at the knots isapproximated by central finite-difference method. The order of convergence of the methodand the theory is illustrated by solving tes...
