Abstract

This paper presents a new iterative algorithm for approximating the fixed points of multivalued generalized \(\alpha\)–nonexpansive mappings. We study the stability result of our new iterative algorithm for a larger concept of stability known as weak \(w^2\)–stability. Weak and strong convergence results of the proposed iterative algorithm are also established. Furthermore, we show numerically that our new iterative algorithm outperforms several known iterative algorithms for multivalued generalized \(\alpha\)–nonexpansive mappings. Again, as an application, we use our proposed iterative algorithm to find the solution of nonlinear Volterra delay integro-differential equations. Finally, we provide an illustrative example to validate the mild conditions used in the result of the application part of this study. Our results improve, generalize and unify several results in the existing literature.
求解非线性volterra时滞积分微分方程的鲁棒迭代方法
本文提出了一种逼近多值广义\(\alpha\) -非膨胀映射不动点的迭代算法。我们研究了我们的新迭代算法的稳定性结果,这是一个更大的稳定性概念,称为弱\(w^2\) -稳定性。建立了该迭代算法的弱收敛性和强收敛性。此外,我们在数值上证明了我们的新迭代算法优于几种已知的多值广义\(\alpha\) -非扩张映射迭代算法。再一次,作为一个应用,我们使用我们提出的迭代算法求非线性Volterra延迟积分微分方程的解。最后,我们提供了一个说明性的例子来验证在本研究的应用部分结果中使用的温和条件。我们的结果改进、推广和统一了现有文献中的一些结果。
