Fibonacci-regularization method for solving Cauchy integral equations of the first kind

Abstract

In this paper, a novel scheme is proposed to solve the first kind Cauchy integral equation over a finite interval. For this purpose, the regularization method is considered. Then, the collocation method with Fibonacci base function is applied to solve the obtained second kind singular integral equation. Also, the error estimate of the proposed scheme is discussed. Finally, some sample Cauchy integral equations stem from the theory of airfoils in fluid mechanics are presented and solved to illustrate the importance and applicability of the given algorithm. The tables in the examples show the efficiency of the method. Ó 2015 Faculty of Engineering, Ain Shams University. Production and hosting by Elsevier B.V.

Control of Accuracy on Taylor-Collocation Method for Load Leveling Problem

“…С. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] Since the data on the load and its forecasts are given in tabular form, we used the approximations of load and its forecasts by a 4th degree polynomials by 10 points for solving Volterra integral equation by Taylor collocations. The result of the work on accurate and forecast data is shown in the figure (2).…”

Distance Fibonacci Polynomials—Part II

“…A few newer results on the classical Fibonacci and Lucas polynomials and their applications can be found in [8][9][10]. It is worth noting that Fibonacci and Lucas polynomials are used for determining approximate solutions of many types of integral equations such as for example Cauchy integral equations, Abel integral equations, Volterra-Fredholm integral equations and others (for details see [11][12][13][14]). Fibonacci numbers and polynomials by their connections with diophantine equations and Hilbert's 10th problem are also closely related with the so-called Pell surfaces studied by the Shaw prize winner J. Kollar [15] due to an important algorithmic embeddability problem for algebraic varieties [16].…”
