In this paper, we propose the triangular orthogonal functions as a basis functions
 for solution of weakly singular Volterra integral equations second
 kind. Powerful properties these and some operational matrices
 are utilized in direct method to reduce equation to
 algebraic equations. The presented does not need any integration
 obtaining constant coefficients. is co...
This paper is concerned with finding approximate solution for the singular integral equations. Relating the singular integrals to Cauchy principal-value integrals, we expand the kernel and the density function of singular integral equation by the sum of the chebyshev polynomials of the first, second, third and fourth kinds. Some numerical examples are presented to illustrate the accuracy and ef...
The commonly used graded piecewise polynomial collocation method for weakly singular Volterra integral equations may cause serious round-off error problems due to its use of extremely nonuniform partitions and the sensitivity of such time-dependent equations to round-off errors. The singularity preserving (nonpolynomial) collocation method is known to have only local convergence. To overcome th...
