Numerical Schemes for the Generalized Abel’s Integral Equations

Abstract

This paper presents and studies two numerical approximations for the generalized Abel’s integral equations (GAIEs). Two numerical schemes such as linear scheme and quadratic scheme are proposed to solve GAIEs numerically. The error convergence of the presented schemes is also established where it is observed that the quadratic scheme achieves the convergence order up to 3. Some examples of GAIEs from literature are considered to perform the numerical investigations and the obtained numerical results are shown in tabular form. We analyze that the presented schemes work well and provide good numerical results. It is also observed that the accuracy in the numerical solutions can be achieved with smaller value of the step size. As the GAIEs reduces to the Abel’s integral equation of the first kind in special case, therefore a similar scheme could be developed to solve such equations. © 2018, Springer (India) Private Ltd., part of Springer Nature.
