Accelerating fixed point algorithms for nonlinear Fredholm integral equations

Chinedu Nwaigwe, Vishnu Narayan Mishra

Published Online: 30 Sep 2024DOI: 10.47974/JIM-1782

In this paper: This paper proposes a simple idea to speed-up the convergence of a fixed-point iteration for Fredholm equation defined on a mesh. First, the analytical problem is discretized by using quadrature rule...
