[HTML][HTML] Optimization of transfinite interpolation of functions with bounded Laplacian by harmonic splines on box partitions

D Kuzmenko, D Skorokhodov - Journal of Approximation Theory, 2016 - Elsevier
We consider the problem of optimal transfinite interpolation of functions with the bounded
Laplacian by harmonic splines on box-partitions. For anisotropic partitions obtained from the …

Sharp asymptotics of the Lp approximation error for interpolation on block partitions

Y Babenko, T Leskevich, JM Mirebeau - Numerische Mathematik, 2011 - Springer
Adaptive approximation (or interpolation) takes into account local variations in the behavior
of the given function, adjusts the approximant depending on it, and hence yields the smaller …

On the Lp-error of adaptive approximation of bivariate functions by harmonic splines

Y Babenko, T Leskevich - Applicable Analysis, 2014 - Taylor & Francis
Interpolation by various types of splines is the standard procedure in many applications. In
this paper we discuss harmonic spline “interpolation”(on the lines of a grid) as an alternative …
