Sharp error estimates for spline approximation: Explicit constants, n-widths, and eigenfunction convergence [PDF]
In this paper, we provide a priori error estimates in standard Sobolev (semi-)norms for approximation in spline spaces of maximal smoothness on arbitrary grids.

Smoothing data series by means of cubic splines: quality of approximation and introduction of a repeating spline approach [PDF]
Cubic splines with equidistant spline sampling points are a common method in atmospheric science, used for the approximation of background conditions by means of filtering superimposed fluctuations from a data series.

Solving time fractional Burgers’ and Fisher’s equations using cubic B-spline approximation method
This article presents a numerical algorithm for solving time fractional Burgers’ and Fisher’s equations using cubic B-spline finite element method. The L 1 formula with Caputo derivative is used to discretized the time fractional derivative, whereas the ...

A spline is a piecewise defined special function that is usually comprised of polynomials of a certain degree. These polynomials are supposed to generate a smooth curve by connecting at given data points.

The B-spline function representation is commonly used for data approximation and trajectory definition, but filter-based methods for nonlinear weighted least squares (NWLS) approximation are restricted to a bounded definition range.

Optimal Approximation of Biquartic Polynomials by Bicubic Splines
Recently an unexpected approximation property between polynomials of degree three and four was revealed within the framework of two-part approximation models in 2-norm, Chebyshev norm and Holladay seminorm.

Neutrosophic B-spline Surface Approximation Model for 3-Dimensional Data Collection [PDF]
Since there are threei membershipi functions: truth, false, and indeterminacyi, geometrical modelingi for B-spline surface approximation including neutrosophic data is particularly difficult to construct.

New Cubic B-Spline Approximation for Solving Linear Two-Point Boundary-Value Problems
In this study, we introduce a new cubic B-spline (CBS) approximation method to solve linear two-point boundary value problems (BVPs). This method is based on cubic B-spline basis functions with a new approximation for the second-order derivative.
