On algebraic trigonometric integro splines

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2019
AbstractIn this paper, we present a new kind of quadratic approximation operator reproducing of both algebraic and trigonometric functions. It is called integro quadratic splines interpolant, which agree with the given integral values of a univariate real‐valued function over the same intervals, rather than the functional values at the knots. Efficient

Quintic B-spline collocation method to solve n-dimensional stochastic Itô-Volterra integral equations

Journal of Computational and Applied Mathematics, 2021
In this paper, the n -dimensional stochastic Ito-Volterra integral equation is numerically solved via quintic B-spline collocation method. To reach this aim, the quintic B-spline interpolation, Gauss–Legendre quadrature formula and Ito approximation are ...

Multivariate Splines and Algebraic Geometry

2015
Multivariate splines are effective tools in numerical analysis and approximation theory. Despite an extensive literature on the subject, there remain open questions in finding their dimension, constructing local bases, and determining their approximation power. Much of what is currently known was developed by numerical analysts, using classical methods,

Algebras of spline approximation sequences

1995
The main goal of the present chapter is to establish stability criteria for the approximate solution of singular integral equations with piecewise continuous coefficients on the real axis. Based on our knowledge of the structure of approximation systems for the singular integral operator we shall construct a Banach algebra of approximation sequences ...

Algebraic properties of discrete box splines

Constructive Approximation, 1987
It is known that the discrete box splines play an important role in the theory of multivariate splines, subdivision algorithms for the computer generation of surfaces, as well as in the theory of partition of numbers. This paper continues the previous works on discrete box splines and subdivision algorithms of \textit{E. Cohen}, \textit{T.

Solution of the foam-drainage equation with cubic B-spline hybrid approach

Physica Scripta
This work presents a robust and efficient numerical stratagem for the study of integer and fractional order non-linear Foam-Drainage (FD) model. The scheme first uses, usual forward difference and the L 1 formula, in integer and fractional cases ...
