This paper is concerned with the solution of generalised linear differential equations of the form \[ x(t)= \tilde{x} + \int_a^t d[A]x +f(t)-f(a), \quad t \in [a,b], \] in a Banach space \(X\). The overall aim is to provide results on the continuous dependence of the solutions on a parameter.
Following preliminaries, in which existing results are reviewed, the main part of the paper presents a sequence of results covering existence, uniqueness, and various technical results on representations of solutions. Section 5 of the paper illustrates how the methods can be applied to deal with linear equations on time scales and among the closing remarks are some suggestions about applications to linear functional differential equations with impulses.
