Discontinuous functional differential equations with delayed or advanced arguments
Rubén Figueroa
We provide new results on the existence of extremal solutions for discontinuous differential equations with a deviated argument which can be either delayed or advanced. The boundar…

Coupled fixed points of multivalued operators and first--order ODEs with state--dependent deviating arguments
Rubén Figueroa, Rodrigo López Pouso
We establish a coupled fixed points theorem for a meaningful class of mixed monotone multivalued operators and then we use it to derive some results on existence of quasisolutions…
