There are, of course, other methods. The RCIP method may be the most competitive method when achievable accuracy is of primary concern. Features and key numerical tools. Theory on the black board. APPROXIMATE SOLUTIONS OF FREDHOLM INTEGRAL EQUATIONS OF THE SECOND KIND WITH SINGULAR KERNELS I. INTRODUCTION Consider a Fredholm integral equation of the second kind f(x) J k(x, y)f(y)dy = g(x), a where f and g are continuous on [a, b]. Such equations have extensive application.

The modified Lagrange method with Chebyshev nodes transforms the equations into linear algebraic equations, and the corresponding numerical solutions are stable forward. Abstract: In this paper, we present a new computational method for solving linear Fredholm integral equations of the second kind, which is based on the use of B-spline quasi-afﬁne tight framelet systems generated by the unitary and oblique extension principles.

### Stability analysis for periodic solutions of fuzzy shunting

The advantage of this algorithm is that, in the process of calculating 2DFPTA to avoid the calculation of the determinant, it can start from the initial value The theory of integral equation is one of the major topics of applied mathematics. The main purpose of this paper is to introduce a numerical method based on the interpolation for approximating the solution of the second kind linear Fredholm integral equation. In this case, the divided diﬁerences method is applied. At last, two numerical 2014-07-29 We consider spectral and pseudo-spectral Jacobi-Galerkin methods and corresponding iterated methods for Fredholm integral equations of the second kind with weakly singular kernel. The Gauss-Jacobi quadrature formula is used to approximate the integral operator and the inner product based on the Jacobi weight is implemented in the weak formulation in the numerical implementation. 4. Solution For Mixed Volterra-Fredholm Integral Equations Of The Second Kind In this section Bernstein polynomials method is proposed to find the solution for Volterra-Fredholm integral equations of the second kind.

Fredholm integral equations of the second kind are much more difficult to solve than ordinary differential equations. Fuzzy Fredholm integral equation of the second kind is one of the main fuzzy equations addressed by many researchers. Wu and Ma [28] investigated the Fuzzy Fredholm integral equation of the second kind, which is one of the first applications of fuzzy integration.

In this section, we give examples of the Fredholm integral equations of the second kind. These examples show that the Algorithm 2 yields good results for a variety of kernels. Example 1.

Differentiate both sides of the equation with respect to x: f′(x)=2(a−4)x+λ∫109tf(t)dt. Since the integral is independent In this paper, the system of Fredholm integral equations of the second kind is investigated by using a modified degenerate kernel method (MDKM).
