Iterative Methods for Generalized von Foerster Equations with Functional Dependence

open access: yesJournal of Inequalities and Applications, 2007
We investigate when a natural iterative method converges to the exact solution of a differential-functional von Foerster-type equation which describes a single population depending on its past time and state densities, and on its total size. On the right-
