C2 Cubic Algebraic Hyperbolic Spline Interpolating Scheme by Means of Integral Values [PDF]
Mathematics, 2022 In this paper, a cubic Hermite spline interpolating scheme reproducing both linear polynomials and hyperbolic functions is considered. The interpolating scheme is mainly defined by means of integral values over the subintervals of a partition of the ...

An algebraic spline model of molecular surfaces for energetic computations. [PDF]
IEEE/ACM Trans Comput Biol Bioinform, 2011 In this paper, we describe a new method to generate a smooth algebraic spline (AS) approximation of the molecular surface (MS) based on an initial coarse triangulation derived from the atomic coordinate information of the biomolecule, resident in the Protein data bank (PDB).

The algebra of the box spline [PDF]
, 2006 In this paper we want to revisit results of Dahmen and Micchelli on box-splines which we reinterpret and make more precise. We compare these ideas with the work of Brion, Szenes, Vergne and others on polytopes and partition functions.Comment: 69 ...

Polynomial Spline Approach for Double Integrals with Algebraic Singularity [PDF]
Journal of Physics: Conference Series, 2013 In this note, cubature formulas are constructed to evaluate the double integrals on the rectangle with algebraic singularity by replacing the density function f(x,y) with the SΔ(P) modified spline function interpolation of type (0,2). Rate of convergence

On the Stability of the Spline-Collocation Difference Scheme for a Semilinear Differential-Algebraic Index System (1,0) [PDF]
Известия Иркутского государственного университета: Серия "Математика", 2018 In the paper, a semi-linear differential-algebraic system of partial differential equations of index (1, 0) with a rectangular domain of definition and compatible initial-boundary conditions is considered.

An algebraic characterization of B-splines [PDF]
Journal of Mathematical Analysis and Applications, 2021 B-splines of order $k$ can be viewed as a mapping $N$ taking a $(k+1)$-tuple of increasing real numbers $a_0 < \cdots < a_k$ and giving as a result a certain piecewise polynomial function. Looking at this mapping $N$ as a whole, basic roperties of B-spline functions imply that it has the following algebraic properties: (1) $N(a_0,\ldots,a_k)$ has
