| Summary: | The aim of this paper is to show the use of the coupled quasisolutions method as
a useful technique when dealing with ordinary differential equations with functional
arguments of bounded variation. We will do this by looking for solutions for a first-order ordinary differential equation with an advanced argument of bounded variation.
The main trick is to use the Jordan decomposition of this argument in a nondecreasing
part and a nonincreasing one. As a necessary step, we will also talk about coupled fixed points of multivalued operators. |
