The College of Education for Pure Sciences at the University of Basrah  organized a scientific lecture entitled (Modified Parity Perturbation Technique and Effective Two-Step Iterative Methods for Solving Nonlinear Models)
The lecture presented by the student (Huda Jabbar Saeed) included
In this work, an iterative estimator-corrector devoid of higher derivatives iterative methods was built to solve the indefinite models
linearity by combining the quadrature formula and the modified symmetry perturbation method. We demonstrate the iterative modalities
It can reach a high order of convergence, which indicates that the efficiency index of the two-step iterative modalities
is 1.587. Some mathematical models are provided to support the effectiveness of the new iterative methods.
