A universal formula for generalized cardinal B-splines
We introduce a universal and systematic way of defining a generalized Bspline based on a linear shift-invariant (LSI) operator L (a.k.a. Fourier multiplier). The generic form of the B-spline is βL = LdL −1δ where L−1δ is the Green’s function of L and where Ld is the discretized version of the operator that has the smallest-possible null space. The cornerstone of our approach is a main construct...
متن کاملOn real-analytic recurrence relations for cardinal exponential B-splines
Let LN+1 be a linear differential operator of order N + 1 with constant coefficients and real eigenvalues 1, . . . , N+1, let E( N+1) be the space of all C∞-solutions of LN+1 on the real line. We show that for N 2 and n = 2, . . . , N , there is a recurrence relation from suitable subspaces En to En+1 involving real-analytic functions, andwithEN+1=E( N+1) if and only if contiguous eigenvalues a...
متن کاملGeneralized Expo - Rational B - Splines
The concept of expo-rational B-spline (ERBS) was introduced in [6] where the ’superproperties’ of ERBS were studied for the first time. In 2006 the first author of the present paper proposed a framework for the generalization of ERBS, the so-called generalized ERBS (GERBS), and considered one important instance of GERBS, the so-called Euler Beta-function B-splines (BFBS) which offered a good tr...
متن کاملOrthogonality of Cardinal B-Splines in Weighted Sobolev Spaces
The cardinal B-splines Bj,n, j ∈ Z, of order n form an orthonormal sequence in the Sobolev space Hn−1,2(R) endowed with the norm ‖f‖2 ω(n) := ∑n−1 μ=0 ωμ(n)‖∂f‖ for certain positive weights ωμ(n). These weights are specified explicitly. Further, an application to approximation theory is discussed.
متن کاملIsogeometric collocation methods with generalized B-splines
We introduce isogeometric collocation methods based on generalized B-splines and we analyze their performance through numerical examples for univariate and multivariate scalarand vector-valued problems. In particular, advection–diffusion and linear elasticity model problems are addressed. The resultingmethod combines the favorable properties of isogeometric collocation and the geometrical and a...
