Differential equations with nonlocal and functional terms has become an active area of research; these terms may occur in the differential equation and/or in the initial or boundary conditions. Their study is driven not only by theoretical interest but also by the fact that these type of problems occur naturally when modeling real-world applications.
This special issue focuses on all aspects of nonlocal and functional terms including discrete and continuous equations, regular, singular and resonant problems and their applications.
