Operational matrix method for solving fractional weakly singular 2D partial Volterra integral equations

The main objective of the present study is to develop the operational matrix for fractional integration. In order to find the numerical solution of non-linear fractional weakly singular two-dimensional partial Volterra integral equations, the operational matrix of the fractional integration of triangular functions was used. By presenting the findings in the form of figures and tables, a deeper investigation and explanation of the proposed approach was provided. In addition, the numerical results show the high reliability and accuracy of the proposed method. (C) 2022 Elsevier B.V. All rights reserved.
