چکیده
The paper deals with the Lagrange interpolation of functions having a bounded variation derivative. For special systems of nodes, it is shown that this polynomial sequence converges with the best approximation order. The L weighted case is also discussed.

متن کاملSome Perturbed Inequalities of Ostrowski Type for Functions whose n-th Derivatives Are Bounded
We firstly establish an identity for $n$ time differentiable mappings Then, a new inequality for $n$ times differentiable functions is deduced. Finally, some perturbed Ostrowski type inequalities for functions whose $n$th derivatives are of bounded variation are obtained.
متن کاملNumerical solution of functional integral equations by using B-splines
This paper describes an approximating solution, based on Lagrange interpolation and spline functions, to treat functional integral equations of Fredholm type and Volterra type. This method can be extended to functional differential and integro-differential equations. For showing efficiency of the method we give some numerical examples.
متن کاملWhat Are the Limits of Lagrange Projectors?
The behavior of interpolants as interpolation sites coalesce is explored in the suitably restricted context of multivariate polynomial interpolation. A Lagrange projector Pτ is, by definition, a linear map on some linear space X of (scalar-valued) functions on some domain T that associates each function f ∈ X with the unique element Pτf in ranPτ that agrees with f at a given (finite) set τ . Th...
متن کاملKernel Interpolation on Manifolds with Bounded Lebesgue Constants
The purpose of this paper is to establish that for any compact, connected C∞ Riemannian manifold there exists a robust family of kernels of increasing smoothness that are well suited for interpolation. They generate Lagrange functions that are uniformly bounded and decay away from their center at an exponential rate. An immediate corollary is that the corresponding Lebesgue constant will be uni...
