Curve network interpolation by $C^1$ quadratic B-spline surfaces
In this paper we investigate the problem of interpolating a B-spline curve network, in order to create a surface satisfying such a constraint and defined by blending functions spanning the space of bivariate $C^1$ quadratic splines on criss-cross ...

Isogeometric Boundary Elements in Electromagnetism: Rigorous Analysis, Fast Methods, and Examples
We present a new approach to three-dimensional electromagnetic scattering problems via fast isogeometric boundary element methods. Starting with an investigation of the theoretical setting around the electric field integral equation within the ...

Lower bounds for the approximation with variation-diminishing splines [PDF]
We prove lower bounds for the approximation error of the variation-diminishing Schoenberg operator on the interval [0, 1] in terms of classical moduli of smoothness depending on the degree of the spline basis.

A Discrete Adapted Hierarchical Basis Solver For Radial Basis Function Interpolation
In this paper we develop a discrete Hierarchical Basis (HB) to efficiently solve the Radial Basis Function (RBF) interpolation problem with variable polynomial order.

On construction of fourth order Chebyshev splines [PDF]
It is an important fact that general families of Chebyshev and L-splines can be locally represented, i.e. there exists a basis of B-splines which spans the entire space.

Univariate spline quasi-interpolants and applications to numerical analysis
We describe some new univariate spline quasi-interpolants on uniform partitions of bounded intervals. Then we give some applications to numerical analysis: integration, differentiation and approximation of ...

Splines with Free Knots, the Heat Equation, and the Gauß Transform [PDF]
The Gauß (or Weierstraß) transform has applications in many fields of applied mathematics. One of its most important properties within approximation theory is the fact that it maps weak Chebychev spaces onto Chebychev spaces.

Basis of splines associated with singularly perturbed advection -diffusion problems [PDF]
Among fitted-operator methods for solving one-dimensional singular perturbation problems one of the most accurate is the collocation by linear combinations of ${1,x,exp{(pm p x)} }$, known as tension spline collocation.
