TY - JOUR AU - Khudhair, Ahmed Ayad AU - Sohrabi, Saeed AU - Ranjbar, Hamid PY - 2024 TI - Numerical solution of nonlinear complex integral equations using quasi- wavelets JO - AIMS Mathematics SP - 34387 EP - 34405 VL - 9 IS - 12 AB - In this paper, we introduced a numerical approach for estimating the solutions of nonlinear Fredholm integral equations in the complex plane. The main problem was transformed into a novel integral equation, which simplified the computation of integrals derived from the discretization technique. The combination of the standard collocation method with periodic quasi-wavelets, as well as their fundamental properties, was utilized to convert the solution of the newly formulated integral equation into a nonlinear complex system of algebraic equations. The convergence properties of the scheme were also presented. Finally, several numerical examples were provided to demonstrate the efficiency and precision of our proposed approach, which also confirmed its superiority over polynomial collocation methods.
