In this paper, we apply the pseudospectral method based on Chebyshev cardinal function to solve parabolic partial integro-differential equations (PIDEs). Since these play a key role in mathematics, physics, and engineering, finding an appropriate solution is important. We use efficient PIDEs, especially for integral part. Unlike when using functions, functions it no longer necessary integrate f...

The focus of this paper is on the numerical solution of linear systems of Fredhlom integral equations of the second kind. For this purpose, the Chebyshev cardinal functions with Gauss-Lobatto points are used. By combination of properties of these functions and the effective Clenshaw-Curtis quadrature rule, an applicable numerical method for solving the mentioned systems is formulated. Some erro...

in this paper we introduce a type of fractional-order polynomials basedon the classical chebyshev polynomials of the second kind (fcss). also we construct the operationalmatrix of fractional derivative of order $ gamma $ in the caputo for fcss and show that this matrix with the tau method are utilized to reduce the solution of some fractional-order differential equations.
